The IL31 (Interleukin 31) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL31. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL31. 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 IL31, 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 IL31 in the samples is then determined by comparing the OD of the samples to the standard curve.

Moisturizing
This lip balm is really nice. I am constantly buying new lip balm, and this has really impressed me. It keeps your lips very moisturized for quite a long time. I thought it was going to be the size of chap stick, but it’s actually the size of an Elmers glue stick, so it’s well worth the price. I will definitely buy again, if I ever run out 😁
