ATRN ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Attractin (ATRN) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Attractin (ATRN) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Involved in the initial immune cell clustering during inflammatory response and may regulate chemotactic activity of chemokines. May play a role in melanocortin signaling pathways that regulate energy homeostasis and hair color. Low-affinity receptor for agouti (By similarity) . Has a critical role in normal myelination in the central nervous system (By similarity) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Attractin (ATRN) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Attractin (ATRN) . 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 Attractin (ATRN), 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 Attractin (ATRN) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
