Anti-CD72 antibodies are used in the immunodetection of the protein CD72 molecule. In humans, the canonical protein has a reported length of 359 amino acid residues and a mass of 40.2 kDa. Its subcellular localization is in the membrane. It is notably expressed in the tonsil, spleen, lymph node, bone marrow, and appendix. CD72 is reported to play a role in B-cell proliferation and differentiation. Post-translational modifications have been described, including phosphorylation and glycosylation. Synonyms for this target antigen include LYB2, B-cell differentiation antigen CD72, CD72 antigen, lyb-2, and CD72b. CD72 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of CD72 antibodies have been mentioned in research publications and have associated citations. Flow Cytometry, Western Blot, and Immunohistochemistry are common applications for these antibodies.
