Comparison of gene expression profiles of E. coli W3110 normal colonies vs. L-form colonies

ABSTRACT: Expression data comparing typical E.coli colonies grown on BHI and BHI+Sucrose+MgSO4 to L-form colonies grown on BHI+Sucrose+MgSO4+Penicillin G. Keywords: one time point DNA microarray analysis of E.coli colonies grown on BHI and BHI+Sucrose+MgSO4 (controls) with L-form colonies grown on BHI+Sucrose+MgSO4+Penicillin G (experimental). An isolated colony of fresh W3110 was grown for 5hrs to log phase, dilutions of the inoculmn were spread onto three media: BHI, BHI+Sucrose+MgSO4, and BHI+Sucrose+MgSO4+Penicillin G to yield isolated colonies. Isolated control colonies which grow overnight were harvested the next day while isolated L-form colonies which do not grow until 48-72 hrs were harvested after 72hrs. All colonies were harvest with a PBS moistened sterile swab and dipped into a sterile
