Anti-Signal-Regulatory Protein beta 2 antibodies enable researchers to detect and measure the Signal-Regulatory Protein beta 2 antigen in biological samples. This target is a reported synonym of the SIRPB2 gene, which encodes signal regulatory protein beta 2. The human version of Signal-Regulatory Protein beta 2 has a canonical amino acid length of 342 residues and a protein mass of 37 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane of cells.
