Polyclonal Antibody- Human HAS2 
Size: 0.2ml (200ug/ml)
Immunogen: Synthetic peptide-KLH
Ig type: Human IgG
HAS1, HAS2 and HAS3 are HA Synthase proteins that synthesize HA (hyaluronan or hyaluronic acid). The extracellular matrix in most vertebrates express HA, which is a high molecular weight linear polysaccharide composed of alternating glucuronic acid and N-acetylglucosamine residues linked by β-1,3 and β-1,4 glycosidic bonds. The three HAS genes show distinct patterns of expression during development and their protein products play significantly different roles in the formation of the HA matrix. Both HAS1 and HAS2 synthesize high molecular-weight HA, whereas HAS3 produces lower molecular weight HA. The expression of the three HAS isoforms is more prominent in growing cells than in resting cells and is differentially regulated by various stimuli suggesting distinct functional roles of the three proteins. 
Anti-HAS2 antibody is a rabbit polyclonal antibody raised against Human HAS2 . This antibody has been selected for its ability to recognize Human HAS2  in immunohistochemiscal staining, non cross-reactive with other members of the family.
