1·Decellularized porcine heart valves were prepared by using Trypsin-ethylenediamine tetraacetic acid and DNase.

利用胰酶-乙二胺四乙酸、核酸酶处理猪心瓣膜制备脱细胞支架。

2·The DNase hypersensitivity assay is higher in resolution at the DNA level and can be done on a large number of cell types since it's just a single assay.

DNase敏感性的ChIP实验是在检测可调控DNA区域更高的精度，已经经过大量的细胞类型测试。
