intercellular adhesion molecule 3

Intercellular adhesion molecule 3 (ICAM3) also known as CD50 (Cluster of Differentiation 50), is a human gene. The protein encoded by this gene is a member of the intercellular adhesion molecule (ICAM) family. ICAM3 is closely related to ICAM1, consists of 5 immunoglobulin domains, and binds LFA1 through its 2 N-terminal domains. This protein is constitutively and abundantly expressed by all leucocytes and may be the most important ligand for LFA-1 in the initiation of the immune response. It functions not only as an adhesion molecule, but also as a potent signalling molecule. ICAM3 has been shown to interact with EZR and Moesin.

Expression system for standard: NS0; Immunogen sequence: Q30-H485, homodimer

Assay Methodology: Quantitative Sandwich Immunoassay

Aviva's human ICAM-3 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for ICAM-3 has been precoated onto 96-well plates. Standards(NS0, Q30-H485, homodimer) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for ICAM-3 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The absorbance of yellow is proportional to the human ICAM-3 amount of sample captured in plate.
