Anti-CD99L2 antibodies are used in the immunodetection of the protein CD99 molecule like 2. In humans, the canonical protein has a reported length of 262 amino acid residues and a mass of 28 kDa. Its subcellular localization is in the cell membrane and is secreted. Up to 6 different isoforms have been reported for this protein. It is notably expressed in cerebrospinal fluid. A member of the CD99 protein family, CD99L2 is reported to play a role in a late step of leukocyte extravasation helping cells to overcome the endothelial basement membrane. Post-translational modifications have been described, including O-glycosylation. Synonyms for this target antigen include MIC2 like 1, MIC2-like protein 1, and CD99 antigen-like protein 2. CD99L2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some CD99L2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
