[求助] 细胞药物实验的问题~~怎么加药

本人准备给贴壁细胞加一个受体的拮抗剂
请问如果做MTT的话要怎么加药啊——
问题一:
有的论坛帖子里写,等细胞贴壁后,把96孔板的培养液都倒掉,然后加药??
是这样的吗?
那细胞没有培养液怎么长啊。。。还要再加培养液吗
还是应该算一下每孔加多少药量,直接往原来的培养液里加?

问题二:用MTT做细胞药物试验的话,用的培养液是不是血清浓度小于10%就可以了?
还是加药作用的那几天都要用纯DMEM培养啊?

For the first one, you need to wait for the cell to grow well and change the medium with fresh one that contain certain concentration of your drugs.

2.I don't think you should remove the serum since most of the cell lines will be arrested in G0 phase if you remove the serum. That kind of cell cycle effect will seriously affect your experiment's result. You can use normal medium with 10% FBS. For me, I haven't heard of that serum is not allowed in MTT cell viability experiment.
