我如何为LIVE/DEAD细胞活力实验准备死细胞对照？

有两种简单的方法。一种是通过60°C放置20分钟热灭活细胞。第二种是将细胞放入70%乙醇。乙醇固定的细胞可以在冰箱中无限期储存直到使用，可达好几年。

1.离心细胞、使细胞沉淀并去除上清
2.固定细胞：在15mL含有细胞团的试管中加入10 mL70%冰乙醇，先开始逐滴加入后震荡，混合均匀。
3.在冰箱中储存直到使用。
4.快使用时，水洗两次且在选择的缓冲液中重悬。

How do I prepare dead cell controls for LIVE/DEAD cell viability assays?

There are two easy options. One is to heat-inactivate the cells by placing at 60 degrees C for 20 minutes. The second is to subject the cells to 70% ethanol. Alcohol-fixed cells can be stored indefinitely in the freezer until use, potentially up to several years.

Centrifuge cells, pellet, and remove supernatant.
Fix cells: Add 10 mL ice cold 70% ETOH to a 15 mL tube containing the cell pellet, adding dropwise at first while vortexing, mix well.
Store in freezer until use.
When ready to use, wash twice and resuspend in buffer of choice.
