You can try reviving them, but I'm skeptical about their survival. If necessary, you can miniprep from the frozen culture to recover plasmid, then re-transform.

Thanks for your reply
What do you mean by miniprep , should i try to culture using same bacterial sol in LB broth and then extract plasmid, if there will be some growth ??

He means you could try to get the plasmids out of the dead cells, so the plasmids arent lost.


ANd indeed, most likely they are dead, but you can still try to revive them.. nothing lost trying..

If you don't know it, then ask it! Better to ask and look foolish to some than not ask and stay stupid.
