The biggest problem in isolating RNA from gram-positive bacteria is the disruption of the cell wall. A lot of protocols employ enzymatic digestion (pretreatment) which may affect gene expression patterns of certain genes. Therefore physical disruption using beads could be the best alternative.

I would like to regulate the expression of a gene and in order to do that, I have purchased specific siRNA. After optimizing my transfection protocol and using electroporation I have achieved a 60-70% reduction of the gene of interest. However, I cannot observe a significant reduction of mRNA expression but only a reduction of protein. What might be the problem? Could the problem be in my cell treatment method?
