The PRF1 (Perforin 1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human PRF1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human PRF1. 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 PRF1, 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 PRF1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Comfortable Stretch Brief
Size: Medium, Color: Red Orange Yellow Blue
I purchased the cotton stretch Briefs for my husband and he says they are not only comfortable, but have a great fit. He’s very athletic and complained about how some of his briefs would shift when running or other activities. These do not! The fabric breaths and stays cool, and no chaffing. We’ll be getting a few more of these Stretch Briefs for sure!
