MD2, a 160-residue accessory glycoprotein, is responsible for the recognition and binding of Gram-negative bacterial membrane component, lipopolysaccharide (LPS).Internalization of pathogen inside the mononuclear phagocytes has also been attributed to MD2 which leads to the clearance of pathogens from the host. MD2 LY96 Protein, Cynomolgus, Recombinant (His) is expressed in E. coli expression system with C-His tag. The predicted molecular weight is 17.97 kDa and the accession number is B3Y6B0.
