一般說明
已验证PluriSTEM 分散酶-II可与PluriSTEM人ES/iPS培养基(SCM130)一起用于人胚胎和诱导多能干细胞的培养和传代。
分散酶-II在多粘芽孢杆菌中产生。
應用
1.用1:20 Matrigel涂层(每孔1.5 ml)涂覆6孔板。 在2-8ºC孵育过夜或在室温涂覆至少30分钟至1小时后再使用。
2.去除基质胶涂层。 每孔添加2 mL完全培养基。
3.去除培养物中的分化区域。
4.吸出培养基。
5.用2 mL PBS洗涤一次。
6.每孔加入1.5 mL 分散酶II。 37ºC孵育7分钟。
7.用2 mL不含Mg和Ca的PBS洗涤2次。
8.向每个孔中加入2 mL完全培养基,并使用细胞刮刀分离菌落。
9.将刮下的细胞收集在15 ml锥形管中。
10800 rpm离心5分钟
11.重悬在适当体积的完全培养基中。 典型的稀释比为1:5 – 1:6,其取决于细胞密度。 细胞在5-6天内可使用PluriSTEM Human ES/iPS培养基进行传代。
