Human CD4 PharmaGenie ELISA Kit (SBRS0384)

Quantitative immunoassay from Assay Genie for measuring human CD4 glycoprotein concentrations in cell culture supernatants, plasma, and serum. Each kit is supplied as a complete assay package containing pre-coated plate strips, biotinylated detection antibody, recombinant protein standards, streptavidin-HRP conjugate, chromogenic substrate solution, and wash buffer. CD4 is a 55 kDa type-I transmembrane glycoprotein expressed on helper T lymphocytes, monocytes, and macrophages, functioning as the co-receptor for MHC class II molecules during antigen recognition. Investigators deploy this kit in immunology and HIV research to monitor helper T-cell status, characterize immune responses, and evaluate immune modulation in cell culture and animal models. The procedure relies on a standard microplate reader for quantitative readout and downstream analysis. All components are intended for research use only, and the kit is shipped refrigerated and stored refrigerated prior to first use.
