Galectin-1 belongs to a large family of carbohyd e-binding Proteins called lectins. Galectin-1can be either monomeric or homodimeric and is found in a wide variety of cells and tissue types. Galectin-1 can control cell growth, prolife ion, induce apoptosis of activated T cells while it can also modulate cytokine secretion or inhibit pro-inflammatory cytokine production. Galectin-1 plays an important role in acute and chronic inflammation. Recombinant Galectin-1 is a non-glycosylated Protein, containing134 amino acids, with a molecular weight of 14.5 kDa.
