N-Acetyl-D-galactosamine (GalNAc) is a terminal essential amino sugar derived from galactose and forms the antigens of blood group A in humans. N-Acetyl-D-galactosamine (GalNAc) interact with Soya bean agglutinin (SBA), hence decreasing the effects of SBA on cellular membrane permeability and tight junction protein expression in piglets[1].N-Acetyl-D-galactosamine (GalNAc) inhibits the hemagglutinating activity by the lectin[2].

In Vitro	N-Acetyl-D-galactosamine (GalNAc) (50nm; 4 hours) decreases the expression of occludin mRNA and claudin-3 mRNA by 1.6% and 2.7%[1]. N-Acetyl-D-galactosamine (GalNAc) (50nm; 4 hours) lowers the protein expression of occludin and claudin-3 by 4.3% and 7.2%, respectively[1]. RT-PCR[1] Cell Line: IPEC-J2 cell Concentration: 50 nM Incubation Time: 4 hours Result: Observed a slight reduction in mRNA expression of occludin and claudin-3. Western Blot Analysis[1] Cell Line: IPEC-J2 cell Concentration: 50 nM Incubation Time: 4 hours Result: Alleviated the damage of tight junction expressions at protein level.
