Anti-LERN2 antibodies enable researchers to detect and measure the LERN2 antigen in biological samples. This target is a reported synonym of the LINGO3 gene, which encodes leucine rich repeat and Ig domain containing 3. The human version of LERN2 has a canonical amino acid length of 592 residues and a protein mass of 64.9 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the tonsil, spleen, and bone marrow.
