Pavilion plunge into heparin

Ting firm use heparin from liver heparin enzyme will produce of flavobacterium from chitterlings mucosa depolymerization and heparin. Major component of the reduction in the side has 2 - O - sulpho - enepyranosuronic acid structure, reduction of the chain, there are 2 - N, 6 - O - disulfonic acid - D - glucosamine structure. The scope of the average molecular weight of 5500 ~ 7500, characteristic value is about 6500. The percentage of the chain quality is not more than 10% less than 2000. The extent of the sulfuric acid salinization is every disaccharide unit 1.8 ~ 2.5. Per mg powder anticoagulant factor Xa activity for 70 ~ 120 u, anticoagulant factor Xa activity and the ratio of the anticoagulant factor II activity is 1.5 ~ 2.5.
