Listed are ELISA Kits for the detection of KAI1, an alias name of CD82 molecule. The human protein, encoded by the gene CD82, is 267 amino acid residues long and has a mass of 29,626 daltons. However, there are up to 2 reported isoforms. It is a member of the Tetraspanin (TM4SF) family. This protein is reported to have a membrane cellular localization, and is glycosylated. This target may also be known as: CD82 antigen, C33 antigen, inducible membrane protein R2, kangai 1 (suppression of tumorigenicity 6 prostate; CD82 antigen (R2 leukocyte antigen antigen detected by monoclonal and antibody IA4)), tetraspanin-27, tspan-27, and 4F9.
