在20 mM丙二酸盐、pH 5.5、1 mM EDTA、400 mM NaCl中冷冻。 溶酶体蛋白酶中最强大的。在降解多种生理蛋白底物方面，它比组织蛋白酶B和H具有更高的比活性。组织蛋白酶L水平是原发性乳腺肿瘤治疗后复发和生存的有力预测因素。 活性：>1单位/mg蛋白质。一个单位定义为在Brij存在下，使用400 mM醋酸钠（pH 5.5）、4 mM EDTA和8 mM DTT作为活化缓冲液，在25℃下每分钟水解1微摩尔Z-Phe-Arg-AFC的酶量。 Frozen in 20 mM Malonate, pH 5.5, 1 mM EDTA, 400 mM NaCl. The most powerful of the lysosomal proteases. It has a higher specific activity than cathepsin B and H in the degradation of a variety of physiological protein substrates. The level of cathepsin L is a strong predictor of relapse and survival following treatment of a primary breast tumor. Activity: > 1 unit/mg of protein. One unit is defined as the amount of enzyme that hydrolyzes one micromole of Z-Phe-Arg-AFC per minute at 25oC using 400 mM Na Acetate, pH 5.5 with 4 mM EDTA and 8 mM DTT as the activation buffer in the presence of Brij.
