These B220 ELISA kits are immunodetection tools for measuring the levels of B220 in biological samples. B220 is an alias of the human PTPRC gene, which encodes the protein, protein tyrosine phosphatase receptor type C. Notably, B220 is known to play a role in B cell differentiation and receptor-mediated signaling pathways, among other functions. The PTPRC protein is 1306 amino acid residues in length and 147.5 kilodaltons in mass. However, as many as 8 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be O-glycosylated. Other names for this target antigen include CD45.
