Recombinant Human CD63 molecule (NP_001771.1) (103-203 aa) was expressed in E. coli 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.
The protein is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility.
