2-octynoic acid-BSA
Based on 1 Customer Validation
NHS-activated 2-octynoic acid-BSA is an immunogen used to establish a mouse model of primary biliary cholangitis (PBC). When used in combination with Complete Freund's Adjuvant (HY-153808), NHS-activated 2-octynoic acid-BSA stimulates the body's immune system, which recognizes it as a foreign antigen and triggers an immune response against autologous biliary epithelial cells. This leads to the production of anti-PDC-E2 antibodies, causing bile duct damage and inflammation. NHS-activated 2-octynoic acid-BSA is promising for use in primary biliary cholangitis research.

Biological Activity
2-octynoic acid (20 min (0°C stirring); overnight (ambient temp warming); 3 h (BSA coupling)) is successfully conjugated to BSA via lysine residues following a multi-step chemical synthesis and purification workflow[1].
