Anti-LGALS3 antibodies are directed against the target, LGALS3. This target gene encodes the protein 'galectin 3' in humans and may also be known as lectin, galactoside binding soluble 3, CBP 35, MAC2, GAL3, 35 kDa lectin, and CBP35. Structurally, the protein is reported to be 26.2 kilodaltons in mass. Based on gene name, canine, porcine, monkey, mouse, and rat orthologs may also be found.
