The Rat IL-21 ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat IL21. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat IL21. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat IL21, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Rat IL21 in the samples is then determined by comparing the OD of the samples to the standard curve.

Amazing Quality & Price
Color: Black Band and Blue Face, Color: Black Band and Blue Face
Exactly as described. It looks absolutely stunning in person. It's very lightweight. Adjustable metal band with tool for ejecting the pins and band pieces. Movement around my wrist feels great and not pinching my arm hairs. Extremely easy to use and set up. Fits perfectly after making some minor adjustments on the band. Battery life promise of 10 years.

Not bad for a watch under 50 bucks
Color: G2856-all silver, Color: G2856-all silver
Im not sure what material this watch is made of but the band doesn’t sound weird, it doesn’t feel like a very solid watch but it really looks fancy and nice i really like it a lot,plus lets be realistic you can have high expectations for 40 bucks, is the first one I bought from this brand, I would like to buy yhe automatic one that is around 150 but i want to try the cheapest one first and see if i like it or not, so far im happy i will update in some time to see how’s holding up

Elegant and affordable—exceeds expectations.
Color: Black Band and Blue Face
⭐⭐⭐⭐☆ (4/5) A very elegant watch offering excellent value for money. The blue design with gold accents looks modern and eye-catching—ideal for any occasion. The materials feel high-quality, and it keeps time with good precision. As a minor note, some of the sub-dials are decorative, and the strap can be a bit tricky to adjust. Overall, a very good purchase for the price. 👍
