CD56(trn)-muIg Purified (with Antibiotics)
Human CD56 is an adhesion molecule from the Ig superfamily which is restricted to NK cells in the immune system. It is believed that NK cells form a first line of defense against tumor cells and cells infected with bacteria and viruses.
Molecular Structure: A soluble fusion protein consisting of the extracellular loop domains 1-4 (370aa) of human CD56 (20)LQVDIV….CTASN(389)
fused to murine IgG2a Fc and hinge (232aa), with a predicted monomeric molecular weight of kd 67.8.
Transfectant Cell Line: CHO
Functional Application: CD56(trn)-muIg fusion protein blocks binding of anti-human CD56 antibody (cat #308-020, but not cat #208-020) to NK cells present in ficoll prepared human PBL.
