Anti-BCL2 like 1 antibodies are used for the immunodetection of the protein encoded by the BCL2L1 gene. In humans, the canonical protein has a reported length of 233 amino acid residues and a mass of 26 kDa. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the Bcl-2 protein family, it is reported to be a potent inhibitor of cell death. Post-translational modifications have been described, including ubiquitination, protein cleavage and phosphorylation. Other names for this target antigen include BCL2L, BCLX, Bcl-X, PPP1R52, bcl-2-like protein 1, and BCL-XL/S. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 2100 citations in the literature describe the use of BCL2 like 1 antibodies in research. Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
