General description
Trypsin is a kind of serine protein hydrolase, exclusive role in composed of alkaline amino acids arginine and leucine peptide bond, soluble in **, insoluble in chloroform, ethanol, ethyl ether, and glycerin, Ca2 + is protection for trypsin and activation function.
Manufacture
Trypsin production of Beijing Geyuantianrun Bio - tech Co., ltd. is by protein chromatography technology preparation, reach the standard pharmaceutical raw materials.
Application
?As pharmaceutical raw materials manufacturing injection, infusion agent, sprays, clinical surgery used for all sorts of inflammation, ulcers, gangrene, an abscess caused by trauma, impotent, edema, hematoma and snake bites. Surgery for the treatment of tinea scabies and other skin disorders. Internal medicine for pyothorax, emphysema, bronchitis, bronchus wheeze, etc; Treatment of diabetic complications, such as nephritis; Treatment of bone disease.
?As a food processing cutting big molecular protein.
?As a proteolytic enzyme is widely applied in biology, medicine and food industries research and development, testing field.

概述
胰糜蛋白酶是糜蛋白酶和胰蛋白酶的混合晶體，具有兩種酶的性質(zhì)。水解酪蛋白的活力與糜蛋白酶相當(dāng)，水解苯甲酰酪氨酸乙酯的活力相當(dāng)于糜蛋白酶的3倍，水解酯鍵的活力與胰蛋白酶相似。干燥情況下穩(wěn)定，液體狀態(tài)易失活，PH7—8時活性最強(qiáng)。
北京格源天潤生物技術(shù)有限公司生產(chǎn)的糜胰蛋白酶是通過多重結(jié)晶方式純化，并進(jìn)一步采取超濾技術(shù)制備而得。
