| Usage |
Experimental equipment required for the experiment: 1. Microplate reader (450nm) 2. High-precision pipette and gun tips: 0.5-10uL, 5-50uL, 20-200uL, 200-1000uL 3. 37℃ constant temperature box 4. Distilled water or deionized water Sample processing and requirements: Serum: Place the whole blood sample collected in the serum separation tube at room temperature for 2 hours or at 4℃ overnight, then centrifuge at 1000×g for 20 minutes, and take the supernatant, or store the supernatant at -20℃ or -80℃, but avoid repeated freezing and thawing. Plasma: Collect the specimen using EDTA or heparin as an anticoagulant. Centrifuge the specimen at 1000 × g for 15 minutes at 2-8°C within 30 minutes of collection. The supernatant can be assayed or stored at -20°C or -80°C, but avoid repeated freezing and thawing. Tissue homogenization: Rinse the tissue with pre-chilled PBS (0.01M, pH 7.4) to remove residual blood (lysed red blood cells in the homogenate will affect the measurement results). Weigh the tissue and mince it. Add the minced tissue to the appropriate volume of PBS (generally a 1:9 weight-to-volume ratio, e.g., 1 g of tissue sample to 9 mL of PBS. The specific volume can be adjusted according to experimental needs and recorded. It is recommended to add protease inhibitors to the PBS) in a glass homogenizer and grind thoroughly on ice. To further lyse tissue cells, the homogenate can be sonicated or repeatedly frozen and thawed. Finally, centrifuge the homogenate at 5000 × g for 5-10 minutes, and the supernatant can be assayed. Cell Lysis Buffer: Gently wash adherent cells with ice-cold PBS, then trypsinize and collect them by centrifugation at 1000×g for 5 minutes. Suspension cells can be collected directly by centrifugation. Wash the collected cells three times with ice-cold PBS and resuspend them in 150-200 μL of PBS per 1×10^6 cells (it is recommended to add protease inhibitors to the PBS; if the cell count is very low, reduce the PBS volume appropriately). Disrupt the cells by repeated freeze-thaw cycles or sonication. Centrifuge the extract at 1500×g for 10 minutes at 2-8°C, and remove the supernatant for analysis. Cell culture supernatant: Centrifuge at 1000×g for 20 minutes, remove the supernatant, or store at -20°C or -80°C, but avoid repeated freeze-thaw cycles. Other biological fluids: Centrifuge at 1000×g for 20 minutes, and remove the supernatant for analysis. Pre-Assay Preparation: 1. Remove the test kit from the refrigerator 10 minutes in advance and equilibrate to room temperature. 2. Prepare the gradient working solution of the standard: Add 1 mL of universal diluent to the lyophilized standard. Let stand for 15 minutes to completely dissolve, then gently mix (concentration is 200 pg/mL). Then dilute to the following concentrations: 200 pg/mL, 100 pg/mL, 50 pg/mL, 25 pg/mL, 12.5 pg/mL, 6.25 pg/mL, 3.125 pg/mL, and 0 pg/mL. Serial Dilution Method: Add 500 μL of universal diluent to each of seven EP tubes. Pipette 500 μL of the 200 pg/mL standard working solution into the first EP tube and mix thoroughly to make a 100 pg/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves directly as a blank well; there is no need to aspirate the liquid from the penultimate tube. See the figure below for details. 3. Preparation of Biotinylated Antibody Working Solution: 15 minutes before use, centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration using universal diluent (e.g., 10µL concentrate + 990µL universal diluent). Prepare immediately before use. 4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately. 5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing). Procedure: 1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C. 2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.) 3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes. 4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used). 5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes. 6. Washing: Discard the liquid and wash the plate five times as in step 4. 7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes. 8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm. Calculating experimental results: 1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis. 2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor. |

| Theory | This kit utilizes a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotinylated detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with Interleukin 1 Alpha (IL-1α) capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by HRP peroxidase and to yellow by acid. The intensity of the color is positively correlated with the amount of Interleukin 1 Alpha (IL-1α) in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration. | |||||||||||||||||||||||||||||||||

| Background | Interleukin-1α (IL-1α), also known as hematopoietin-1, is a cytokine in the interleukin-1 family, encoded by the IL-1α gene. Generally, interleukin-1 is responsible for producing inflammation and promoting fever and sepsis. IL-1α inhibitors are currently under development to disrupt these processes and treat disease. IL-1α is primarily produced by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It has metabolic, physiological, and hematopoietic activities and plays a central role in regulating immune responses. It binds to the interleukin-1 receptor, which is involved in the activation of tumor necrosis factor-α. The mouse IL-1α cDNA encodes a 270-amino acid pro-IL-1α precursor peptide containing a nuclear localization sequence, an N-acylation site, and three potential N-linked glycosylation sites. Most IL-1α is retained in the cell in the form of precursor proteins, and a portion of unprocessed IL-1α is transported to the cell surface. These membrane-bound unprocessed IL-1α also have certain biological activity and can act on the IL-1 receptors on the surface of adjacent cells in a paracrine manner. | |||||||||||||||||||||||||||||||||
| General Notes | 1. Strictly adhere to the specified incubation time and temperature to ensure accurate results. All reagents must be at room temperature (20-25°C) before use. Refrigerate reagents immediately after use. 2. Improper plate washing may result in inaccurate results. Ensure that all liquid in the wells is aspirated thoroughly before adding substrate. Do not allow the wells to dry out during incubation. 3. Remove any residual liquid and fingerprints from the bottom of the plate, as this will affect the OD value. 4. The substrate developer solution should be colorless or very light in color. Do not use substrate solution that has turned blue. 5. Avoid cross-contamination of reagents and specimens to prevent erroneous results. 6. Avoid direct exposure to strong light during storage and incubation. 7. Do not expose any reagents to bleaching solvents or the strong fumes emitted by bleaching solvents. Any bleaching agent will destroy the biological activity of the reagents in the kit. 8. Do not use expired products, and do not mix components with different product numbers and batches. 9. Recombinant proteins from sources other than the kit may not be compatible with the antibodies in this kit and will not be recognized. 10. If there is a possibility of disease transmission, all samples should be managed properly and samples and testing devices should be handled according to prescribed procedures. |

Delicious and Healthy Snack with Unmatched Flavor and Texture
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
As someone who is constantly on the lookout for tasty and healthy snacks, I recently came across these Droewors Beef Sticks, and I have to say, I'm truly impressed. The unique air-drying process, combined with the use of vinegar, cloves, and coriander, gives these beef sticks a fantastic flavor that is not only mouth-watering but also worlds apart from other meat sticks I've tried in the past.
Pros:
Unique Flavor - The combination of spices and the air-drying process creates a taste that is both savory and satisfying.
Texture - The coarse ground beef provides a buttery smooth texture that doesn't leave your hands greasy, unlike other meat sticks.
Keto, Paleo, and Whole 30 Friendly - These beef sticks fit well with a variety of diets, making them a versatile snack option.
High Protein Content - With more protein per ounce than other meat sticks, they're a great natural alternative to protein shakes for muscle fuel.
No Sugar - The absence of sugar means no sugar rushes or mood swings, making it a great option for a healthy diet.
Cons:
Price - These beef sticks might be a bit more expensive than other brands due to their high-quality ingredients and production process. However, I believe the unique flavor and health benefits make the price justifiable.
In conclusion, these Droewors Beef Sticks are a delicious and healthy snack option for those following Keto, Paleo, or Whole 30 diets, or simply looking for a tasty protein-packed snack. The unique flavor and texture, coupled with the high protein content and absence of sugar, make these beef sticks stand out from the crowd. While they may be a bit pricier than other meat sticks, the quality and taste make it well worth the investment. Highly recommended!

Good Food
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
I have had South African Billtong before and I loved it, so I thought I would try SA Droewars and see if they were as satisfying. The answer is yes! They are delicious and nothing like your typical mass marketed jerky snacks sold in the US. Droewars are lightly seasoned beef jerky sticks and, although I have not seen the numbers, they seem to be only lightly salted (important for me). The meat is not chewy or grisly, so the beef cuts they use must be prime.
This is the first time I have tried the Ayoba-Yo brand and I am happy with my purchase. I am awaiting delivery of several varieties of Billtong from Ayoba-Yo presently and I will report back.
Not inexpensive, but the value is there for sure.

Almost not edible
Flavor Name: Traditional, Size: 2 Ounce (Pack of 3), Flavor Name: Traditional, Size: 2 Ounce (Pack of 3)
I am south african, an afrikaaner. I grew up eating droewors and biltong. I'm not sure what went wrong with this product. I have to believe it was off quality product and not what they are choosing to ship. The flavor was ok. Nothing spectacular. Thr big issue was texture of the droewors and the fact that the meat had shrunk away from the casing leaving the casing inedible. See my pic. This is not what droeworse looks like. Also, being from south africa I've never heard anyone say the word ayoba....
