由重组胶原酶混合组分和耐热金属蛋白酶组成,其中重组胶原酶混合组分采用E.coli表达,对胶原蛋白特有的氨基酸序列Pro-X-Gly-Pro中的中性氨基酸 (X) 和甘氨酸之间的键具有特异性;耐热金属蛋白酶采用E.coli进行重组表达,可以水解疏水性氨基酸残基N-末端的蛋白质键。重组胶原酶混合组分和耐热金属蛋白酶均不含动物源成分,同时使用可以高效的消化肠道、心脏、肝脏、肾脏等动物器官,获得相对应的原代细胞。与采用胰蛋白酶的试剂盒相比,耐热金属蛋白酶的活性不受血清影响,更加适合在消化过程中需要加血清的场景。

- Collagenase activity definition: Within 5 hours, at pH 7.4, 37 °C and in the presence of calcium ions, the amount of enzyme that releases peptides from bovine Achilles tendon collagen and the ninhydrin color is equivalent to 1.0 µmol of leucine is 1 CDU. Thermostable metalloproteinase activity definition: at pH 7.5 and 37 °C, the amount of enzyme required to hydrolyze casein and produce 1.0 μM (181 μg) tyrosine per minute is 1U.
