| Description | Human Cluster of differentiation 4 (CD4) ELISA Kit has high sensitivity and excellent specificity for detection of Human CD4. No significant cross-reactivity or interference between Human CD4 and analogues was observed. CD4 (cluster of differentiation 4) is a glycoprotein expressed on the surface of T helper cells, regulatory T cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 monoclonal antibody that reacted with it) before being named CD4 in 1984.In humans, the CD4 protein is encoded by the CD4 gene. CD4 is a co-receptor that assists the T cell receptor (TCR) to activate its T cell following an interaction with an antigen presenting cell. Using its portion that resides inside the T cell, CD4 amplifies the signal generated by the TCR by recruiting an enzyme, known as the tyrosine kinase lck, which is essential for activating many molecules involved in the signaling cascade of an activated T cell. This Human Cluster of differentiation 4 (CD4) ELISA Kit employs a two-site sandwich ELISA to quantitate CD4 in samples. An antibody specific for CD4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyCD4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CD4 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CD4 bound in the initial step. The color development is stopped and the intensity of the color is measured. |
