Reagent Preparation: 1. Melting of reagents: Take out the reagents the day before the experiment and place them at 4 °C overnight to melt. The reagent can also be taken out on the day of the experiment and melted at room temperature, or melted in a 22 °C water bath, but it should be noted that the water temperature should not exceed 25 °C. 2. Equilibrate to room temperature: If the reagent melts at non-room temperature conditions, it can be placed in a 22 °C water bath before use to ensure that the reagent is balanced to room temperature before being used for testing. Note: Generally, it takes about 10 minutes for 5mL packaging; The 50 mL packaging takes about 20 minutes. 3. Mix well: Gently invert the solution 5 times before use to mix the solution evenly. Detection Procedure: 1. Use a 96-well plate suitable for chemiluminescence detection, and add microtissue containing cell culture medium to it. Note: (1) The prepared sample volume and microtissue characteristics (e.g., size, quantity, culture days, etc.) should be optimized for experimental conditions; (2) The total ATP content of the sample should be kept below 10μM (determine the upper limit concentration of the linear range); (3) The multi-well plate must be compatible with the photometer used. 2. Add test compounds to experimental wells and incubate according to your culture protocol. Note: Ensure that the volume of sample and test compound is low enough to allow the addition of equal volumes of reagent and then mixing without inter-well contamination. 3. Equilibrate the plate and its contents to room temperature (22-25 °C) for about 30 minutes. 4. Add 3D Reagent equal to the volume of cell culture medium present in each well to the detection well (e.g., for a 96-well plate, add 100 μl of 3D Reagent to 100 μl of cell-containing culture medium). 5. The contents were vigorously mixed for 5 minutes to induce cell lysis. Note: Mixing is important for efficient ATP extraction from 3D microtissues. 6. Allow the plate to incubate at room temperature for another 25 minutes to stabilize the luminescence signal. 7. Record luminescence. Note: The non-uniform luminescence signal within the plate may be caused by temperature gradients, non-uniform cell seeding, or edge effects in multi-well plates. |
| Description | 3D cell cultures are more physiologically relevant and better representative of tissues in vivo, allowing more accurate predictions of efficacy or toxicity of drug treatments. 3D cell models are increasingly being used to understand disease mechanisms and discover drug therapies. Compared with 2D culture, 3D cell culture can predict the efficacy or toxicity of drug treatment more accurately. 3D Luminescent Cell Viability Assay Kit is a cell viability detection reagent based on luciferase system. It uses ATP-dependent luciferase-catalyzed luciferin luminescence reaction to measure intracellular ATP content through chemiluminescence signal to detect cell viability. The detection has wide linear range, high sensitivity and good stability. Due to the high-purity luciferin substrate, thermostable luciferase and optimized reaction reagents in this kit, this product has stronger cell lysis ability and can be used for cell viability analysis of 3D microtissue culture. This product is added to the cell culture to lyse the cell mass and release ATP, which can produce the reaction as shown in the figure and send out a stable light signal. The luminescence intensity is directly proportional to the amount of ATP, that is, the number of viable cells, within a certain range, so this product can quantitatively detect the number of viable cells. PRODUCT FEATURES The 3D Luminescent Cell Viability Assay has high detection sensitivity and wide linear range, and is compatible with small sample detection and high-throughput screening of large samples. 1. Convenient and fast: The detection reagents provided in the kit are ready-to-use, with stable readings and fast detection speed. It only takes about 10 minutes to complete the detection; 2. High sensitivity: It has a higher signal-to-noise ratio when applied to 3D microtissue detection; 3. Fast: data can be recorded within 30 minutes or less after adding reagents; 4. The luminescent signal is more stable: the half-life of the luminescent signal is ultra-stable, usually > 3 hours. 5. Stronger lysis ability: The optimized reaction reagent has stronger cell lysis ability and is suitable for cell viability analysis of 3D microtissue culture; 6. High throughput: It is compatible with the detection of a small amount of samples and the high throughput screening of a large number of samples. |
| General Notes | 1. Temperature: The reagent contains luciferase, and repeated freezing and thawing will affect its activity. It is recommended to store at-20 ℃ in the dark from light after dispensing. Reagents and cell samples should be balanced to room temperature before use to avoid the influence of enzyme catalytic effect; 2. Chemical factors: The reaction rate and luminous intensity of luciferase are affected by the chemical environment. There are differences in luminescence intensity and attenuation rate among different types of media and serum. In addition, high drug content may interfere with the luciferase reaction, thus affecting the luminescence signal. It is recommended to set up control wells of cell culture medium containing drugs to eliminate the interference of solvents; 3. Light sensitivity: This reagent is sensitive to light. If it is exposed to light during storage, it will accelerate the attenuation of luminous intensity. If the reagent is transferred from the original container, make sure to keep it protected from light; 4. ATP contamination: It is recommended to wear masks and latex gloves during operation to avoid contact with surfaces and equipment that may be contaminated. Avoid inserting the tip of the gun tip into the vial multiple times during operation. |

Great Sunscreen at a Great Price!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Love this sunscreen. I live in FL and like to walk most mornings, and need a good sunblock. This Amazon Basics is far better than my previous, far more expensive brand. It's a great price for great quality. I've been using it on my body & face, it's non-greasy, absorbs well, and really seems to offer very good sun protection. And I really appreciate the next day shipping on my past two orders, Amazon. Thanks for the great product & great service!

Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Great for the face, lightweight and no white residue.
Size: 3 Fl Oz (Pack of 1)
This sunscreen is great for the face as it doesn't leave a whitish residue like some brands, also I find it does not make me feel as hot. It is "lightweight" and goes on easily. It does not seem to stain clothes as much as others I have used in the past. I which they made it in an even higher SPF!
