Human Cluster Of Differentiation 4 (CD4) ELISA Kit

The Assay Genie Human Cluster Of Differentiation 4 (CD4) ELISA Kit enables quantitative measurement of CD4 glycoprotein concentrations in human research samples. CD4 is a 55 kDa transmembrane receptor expressed primarily on helper T lymphocytes, monocytes, macrophages, and dendritic cells, where it serves as a co-receptor for MHC class II molecules and as the primary docking site for HIV-1 entry into host immune cells.

Researchers investigating immune function, T-cell activation dynamics, autoimmune disease mechanisms, and HIV pathogenesis rely on reproducible CD4 quantification to monitor immune status and therapeutic response across longitudinal studies. The kit ships as a complete microplate package containing pre-coated capture antibodies, biotinylated detection antibodies, streptavidin-HRP conjugate, chromogenic substrate solution, and lyophilized recombinant standards, sufficient for processing up to 96 reactions in a single experimental run.

Investigators may apply the assay to tissue homogenates, cell lysates, cell culture supernatants, and ex vivo circulating immune cell suspensions, supporting both in vitro and in vivo immunology workflows. Each plate is packaged in a sealed foil pouch with desiccant to protect unused wells for repeat experiments. For research use only; not intended for diagnostic or therapeutic applications.
