Human CD83 (Cluster Of Differentiation 83) Microsample ELISA Kit

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 Human CD83. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CD83. 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 CD83, 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 CD83 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 78.13-5000 pg/mL. Sensitivity: 18.5 pg/mL. Assay Type: Sandwich. Standard: 5000 pg/mL. Sample Type: sSerum, plasma, cell lysates and other biological fluids.. Assay duration: 3.5h. Protein Function: Transmembrane glycoprotein predominantly found on the surface of many immune cells including dendritic cells or lymphocytes that plays various roles in immune response regulation. Plays an essential role in CD4(+) T-selection, differentiation and stability by regulating the activity of the major E3 ubiquitin ligase responsible for controlling MHCII trafficking MARCHF8. Also inhibits MARCHF1 association with MHCII or CD86 to prevent their ubiquitination and subsequent degradation (PubMed:21220452). In addition, acts as an important modulator of protective responses against acute infections (By similarity) [The Uniprot Consortium]
