help - (Nov/26/2007 )

We've construct the cDNA library by using CloneMiner cDNA Library Construction Kit (Invitrogen). After the construction, we're able to obtain high number of titers. Then, we decide to further the analysis by doing express sequence tag (EST). Anyway, we're having problem to get the plasmid. We didn't get any plasmid after extraction. The LB broth, LB agar and antibiotic which is kanamycin are in good condition. There's some situation, that even the bacteria are having problem to grow in the LB broth. Do you have any suggestion? At the moment, I don't have any ideas how to troubleshoot this problem. And my friends also didn't have any clue as this problem is quite strange to us.

"help" is the poorest title i have ever heard. You need to make an effort to make your title more descriptive, it tells you to do that when you make a new post
