Resumo(s)
The identification of differentially expressed genes is a key step in the understanding of specific molecular mechanisms. Various methods have been developed to search for differences in expression but most of them are time or money consuming. We present here an alternative technique that connects standard suppression subtractive hybridization with in situ screening of bacteria to isolate and identify differentially expressed transcripts. The in situ differential screening is based on the transfer of bacteria directly from cultures onto nylon membranes with no need of phenol/chloroform extraction, colony lifting, or polymerase chain reaction amplification. This improved method was successfully applied and must be seen as a simple, low-cost, time-saving, and reproducible approach to identify differentially expressed genes.
