Anti-FCRL2 antibodies are used in the immunodetection of the protein Fc receptor like 2. In humans, the canonical protein has a reported length of 508 amino acid residues and a mass of 55.5 kDa. Its subcellular localization is in the cell membrane. Up to 5 different isoforms have been reported for this protein. It is reported to be expressed in the secondary lymphoid organs, spleen and lymph node. FCRL2 is believed to have an regulatory role in normal and neoplastic B cell development. Post-translational modifications have been described, including O-glycosylation and phosphorylation. Synonyms for this target antigen include IFGP family protein 4, SH2 domain containing phosphatase anchor protein 1, fc receptor homolog 2, immune receptor translocation-associated protein 4, and Fc receptor-like protein 2. FCRL2 gene orthologs have been reported in the mouse species. A number of FCRL2 antibodies have been mentioned in research publications and have associated citations. Flow Cytometry is a widely used application for these antibodies. ELISA and Western Blot are also common applications.
