Anti-IL2 antibodies are used in the immunodetection of the protein interleukin 2. In humans, the canonical protein has a reported length of 153 amino acid residues and a mass of 17.6 kDa. It has been described to be a secreted protein. A member of the IL-2 protein family, IL2 is known to be involved with adaptive immune responses and cell adhesion. Post-translational modifications have been described, including glycosylation. The IL2 marker can be used to identify CD4 Memory T Cells and Effector Memory CD45RA CD4 T Cells.* Synonyms for this target antigen include lymphokine, T cell growth factor, aldesleukin, involved in regulation of T-cell clonal expansion, and TCGF. IL2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species.
