Anti-LINX antibodies enable researchers to detect and measure the LINX antigen in biological samples. This target is a reported synonym of the ISLR2 gene, which encodes immunoglobulin superfamily containing leucine rich repeat 2. This protein is known to function in nervous system development, among other biological roles. The human version of LINX has a canonical amino acid length of 745 residues and a protein mass of 79 kilodaltons. It is reported to be localized in the cell membrane of cells.
