Anti-absent in melanoma 1-like antibodies enable researchers to detect and measure the absent in melanoma 1-like antigen in biological samples. This target is a reported synonym of the CRYBG2 gene, which encodes crystallin beta-gamma domain containing 2. The human version of absent in melanoma 1-like has a canonical amino acid length of 1661 residues and a protein mass of 177.9 kilodaltons. Other names for this target antigen include AIM1L, AIM1L, and beta/gamma crystallin domain-containing protein 2.
