Recombinant Human CD59 molecule (NP_000602.1) (26-102 aa) was expressed in Yeast with a 6xHis-tag at the N-terminus. The biological activity was determined by its binding ability in a functional ELISA. This product can be used in ELISA, WB, IP.
This protein is a cell surface glycoprotein that regulates complement-mediated cell lysis, and it is involved in lymphocyte signal transduction. This protein is a potent inhibitor of the complement membrane attack complex, whereby it binds complement C8 and/or C9 during the assembly of this complex, thereby inhibiting the incorporation of multiple copies of C9 into the complex, which is necessary for osmolytic pore formation.
