Anti-F-LAN-1 antibodies enable researchers to detect and measure the F-LAN-1 antigen in biological samples. This target is a reported synonym of the DERL2 gene, which encodes derlin 2. This protein is known to function in the regulation of cell proliferation, among other biological roles. The human version of F-LAN-1 has a canonical amino acid length of 239 residues and a protein mass of 27.6 kilodaltons. It is reported to be localized in the ER of cells and widely expressed in many tissue types. Other names for this target antigen include CGI-101, DERtrin-2, and F-LAN-1.
