Stability/Storage: Elastase is unstable at pH ≤ 3.5. When stored as a dry powder the enzyme is stable for 6-12 months at 2-8°C.  Elastase product codes: ES ａnd ESL have poor solubility at neutral pH ａnd at concentrations greater than 0.25%.  It is helpful to make primary solutions in KCl or alkaline buffers before diluting into the reaction mixtures or media, compensating for ionic strength or pH changes.  Stable at pH 4.0-10.4.

Technical Notes: 1 SucAla3NA unit is approximately equivalent to 6 elastin digestion units. Aqueous liquid suspensions should be aseptically handled to avoid bacterial contamination. Due to the viscous nature of the aqueous suspension (Code: ES) the vial should be rinsed to recover contents.

Unit Definition: One Unit cleaves one micromole of N-succinyl-L-alanyl-L-alanyl-L-alanine-p-nitroanilide per minute at 25°C, pH 8.0.

艾美捷Worthington弹性蛋白酶的应用：

组织解离：因为弹性蛋白在结缔组织的弹性纤维中的浓度高，所以经常使用弹性蛋白酶解离含有广泛细胞间纤维网络的组织。为此，它通常与其他酶起使用，例如胶原酶、胰蛋白酶和胰凝乳蛋白酶。
