MEFs - (Feb/24/2009 )
Hi,
i'm newbie for cell culture. today when i was preparing mouse embryonic fibroblasts, after mincing the embryo, by mistake instead of trypsin i let the tissue in pensillin+strepto+glutamin for 10 min. once i realized my mistake, i centrifuged it briefly and then washed in PBS and then suspended it in trypsin. My question is, will this mistake be a problem or its ok.
another thing is after how much time i can see fibroblasts adhering to the surface?
thanks in advance

MEFs are robust cells, so I don't see any problem with the time lapse. I would however worry if your antibiotics were 100X conc.
You will anyway see if MEFs are growing the next day. So, by now you should know the answer.

fibroblasts adhere within 30-35 min on gelatinized plates and this method is usually used to remove MEF feeder cells from co-culture with stem cells
