The F-TESTO (Free Testosterone) ELISA immunoassay kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with F-TESTO. Standards or samples are added to the appropriate micro ELISA plate wells then with a biotin-conjugated antibody specific to F-TESTO. Next,Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of F-TESTO in the samples is then determined by comparing the OD of the samples to the standard curve.

Buy a different one
Color: White
It looks nice but the trimming is garbage. The smaller trimmer l like for eyebrows or close shaving facial hair is worthless. You cannot get close enough nor can you see what you’re doing. You also cannot get right on the edge for precise edges for eyebrows for instance because of how it’s made. The seller does not allow for simple drop off returns either. Too much of a hassle to print labels and too costly for ups pick up. A waste of $20. Buy something else.

Great Product
Color: White
I’m honestly really happy with this purchase! This 3-in-1 bikini trimmer came exactly as expected and works super well. It’s easy to use, lightweight, and doesn’t feel cheap at all. I like that it comes with different attachments so you can switch it up depending on what you need—that’s a big plus. It trims smoothly without pulling or irritating my skin, which was something I was worried about, but it handled everything gently. The design is cute and simple, and it’s easy to clean after using it too. For the price, it’s definitely worth it—you get good quality without spending a lot. Shipping was on time and everything came in good condition. Overall, I’d definitely recommend this if you’re looking for something affordable that still gets the job done right!

Very good toothbrush that your cat can chew to help clean his teeth
These are silicone pet toothbrushes. What they work really well for, is letting your cat chew to clean their own teeth (once you put some tasty fish toothpaste on it). It's so difficult to find things the cats will actually chew on in this way and the fact that its silicone (soft but not easily broken) is perfect. I recommend just holding the other end and encouraging the cat to chew on the silicone part, while adding toothpaste as needed. I've only convinced one of my cats to do this, but he loves it! I use a different smaller and softer brush to actually brush with and combined, this seems to be making a big difference for the plaque and his breathe. Very happy I found these and will repurchase as needed.
