Anti-CD24 antibodies are used in the immunodetection of the protein CD24 molecule. In humans, the canonical protein has a reported length of 80 amino acid residues and a mass of 8.1 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the CD24 protein family, CD24 is suspected to have a pivotal role in cell differentiation of different cell types. Post-translational modifications have been described, including O-glycosylation. The CD24 marker can be used to identify Transitional B Cells.* Synonyms for this target antigen include signal transducer CD24 and CD24 antigen (small cell lung carcinoma cluster 4 antigen). CD24 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species.
