Mr M heparin from pigs, intestinal mucosa for heparin by alkaline decomposed. Its main ingredients include a 2 - O - sulfo - 4 - enepyrano - suronic acid structure in the end, and a 2 - N, 6 - O - disulfo - D - glucosamine structure in the end of the chain of reduction. The average molecular weight of 3600 (3000 ~ 4200). The degree of sulfating usually each disaccharide unit of 2.
Heparin is a highly sulfated glycosaminoglycan anticoagulant produced via enzymatic extraction from porcine intestinal mucosa. Its molecular formula is C4H7O11Sn (variable) with CAS No. 9005-49-0.
Strict monitoring of activated partial thromboplastin time (aPTT) is required. Store at 2°C–8°C in original packaging to maintain potency and prevent microbial contamination.
