Anti-SPACRCAN antibodies enable researchers to detect and measure the SPACRCAN antigen in biological samples. This target is a reported synonym of the IMPG2 gene, which encodes interphotoreceptor matrix proteoglycan 2. This protein is known to function in extracellular matrix organization and protein localization, among other biological roles. The human version of SPACRCAN has a canonical amino acid length of 1241 residues and a protein mass of 138.6 kilodaltons. It is reported to be localized in the extracellular matrix of cells and notably expressed in the retina.
