Anti-lectin, galactoside binding soluble 9B antibodies enable researchers to detect and measure the lectin, galactoside binding soluble 9B antigen in biological samples. This target is a reported synonym of the LGALS9B gene, which encodes galectin 9B. This protein is known to function in the regulation of gene expression, among other biological roles. The human version of lectin, galactoside binding soluble 9B has a canonical amino acid length of 356 residues and a protein mass of 39.7 kilodaltons, although 2 isoforms have been identified. It is reported to be notably expressed in the stomach, rectum, gallbladder, colon, and appendix.
