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。水解酪蛋白的活力與糜蛋白酶相當，水解苯甲酰酪氨酸乙酯的活力相當于糜蛋白酶的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。

北京格源天潤生物技術有限公司生產(chǎn)的糜胰蛋白酶是通過多重結晶方式純化，并進一步采取超濾技術制備而得。

用途

臨床于治療各種炎癥、炎性水腫、血腫、術后粘連、潰瘍、血栓等，對慢性支氣管炎、哮喘、胃炎、宮頸炎、盆腔炎、化膿性中耳炎、前列腺炎、栓塞性靜脈炎、腦血栓形成等均有一定療效。
應用于現(xiàn)代工業(yè)領域，如作為高級皮革的脫毛、軟化劑。
作為實驗室分析試劑，被科研院校廣泛應用。
