$ ]3 z, l# A* e t! i0 Q- i昨天与一个师兄探讨了下,我觉得可能跟我的消化时间还有处理方式有关系,我一般是消化30min,等待完全漂浮起来之后再去直接中和,昨天探讨完之后我又看下dispase说明书,结果就是下次消化的时候可以缩短消化时间,30变为10min,之后吸取酶,放进培养箱中在放置5min左右,再中和,再吹打带刮除,另外,你觉得培养基的PH值会不会对细胞的生长构成影响呢,我测的我的培养基PH7.5-7.6只见了都,新鲜配的7.35-7.48之间

Description
: B; m4 f. a8 M2 m) CDispase, or neutral protease, is a metalloenzyme produced by Bacillus polymyxa which has been classified as an amino-endopeptidase. This enzyme has proven to be a rapid and gentle agent for the harvest and transfer of normal diploid cells and cell lines. In addition, Dispase has been shown to effectively separate cell clumps, as well as cells from intact tissue without significantly affecting cell membrane integrity or viability.
