CCR4 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Chemokine C-C-Motif Receptor 4 (CCR4) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Chemokine C-C-Motif Receptor 4 (CCR4) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

C-C chemokine receptor type 4; C-C CKR-4; CC-CKR-4; CCR-4; CD194; chemokine (C-C motif) receptor 4; chemokine (C-C) receptor 4; ChemR13; CKR4; CMKBR4; HGCN:14099; K5-5.

High affinity receptor for the C-C type chemokines CCL17/TARC, CCL22/MDC and CKLF isoform 1/CKLF1. The activity of this receptor is mediated by G (i) proteins which activate a phosphatidylinositol-calcium second messenger system. Can function as a chemoattractant homing receptor on circulating memory lymphocytes and as a coreceptor for some primary HIV-2 isolates. In the CNS, could mediate hippocampal-neuron survival.

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 Chemokine C-C-Motif Receptor 4 (CCR4) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Chemokine C-C-Motif Receptor 4 (CCR4) . 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 Chemokine C-C-Motif Receptor 4 (CCR4), 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 Chemokine C-C-Motif Receptor 4 (CCR4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
