Anti-clusterin-like 1 (retinal) antibodies enable researchers to detect and measure the clusterin-like 1 (retinal) antigen in biological samples. This target is a reported synonym of the CLUL1 gene, which encodes clusterin like 1. The human version of clusterin-like 1 (retinal) has a canonical amino acid length of 466 residues and a protein mass of 54.2 kilodaltons. It is reported to be a secreted protein that is notably expressed in the retina. Other names for this target antigen include RA337M, clusterin-like protein 1, and clusterin-like 1 (retinal).
