The CD4 (Cluster Of Differentiation 4) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CD4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CD4. 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 Human CD4, 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 Human CD4 in the samples is then determined by comparing the OD of the samples to the standard curve.

Fair quality shirt
Size: Large, Color: Port Red
Decent shirt. No shirt if wrinkle-free so take these claims with a grain of salt. The fabric blend will tell you just how much it will wrinkle. If you leave it in the dryer overnight you can guarantee that even if it was made of cast iron, it would likely have a wrinkle or two. Don't be swayed by a 'label'. The same shirt can have a no-name label sewn on it. Doesn't make the shirt better or worse. It is what it is. Size runs correct. NOT a 'slim fit' shirt, fyi.

Two tone color
Color: Silver GunColor, Color: Silver GunColor
I guess it’s good enough for what you pay but the band and base of the watch color do not match and it’s noticeable.
