5 X 105 cultured human Jurkat cells per tube were washed and preincubated ~5 minutes on ice with 20 ml of 250 mg/mL human IgG (to block non specific binding) after which they were incubated 45 minutes on ice with 80 ml of ICAM3 monoclonal antibody, clone 186-2G9 (Cat # MAB6936) at 10 mg/mL. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed using a BD FACS Calibur. Cells stained positive with a mean shift of 1.84 log10 fluorescent units when compared to a Mouse IgG2b negative control at a similar concentration.
The protein encoded by this gene is a member of the intercellular adhesion molecule (ICAM) family. All ICAM proteins are type I transmembrane glycoproteins, contain 2-9 immunoglobulin-like C2-type domains, and bind to the leukocyte adhesion LFA-1 protein. 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. [provided by RefSeq
