Isolation of total RNA from Bacillus Subtilis using phenol-chloroform extraction method by maintaining cryogenec conditions initailly to prevent RNA degradation. Quality of the obtained RNA is then tested with Agilent Bioanalyser before proceeding for gene expression analysis.
The phosphorylation level of a particular protein can be determined using a procedure based upon western immunoblotting, with Phos-tag™ reagent present in the SDS-PAGE gel. The Phos-tag™ reagent, supplied in the form of Phos-tag™ acrylamide (Wako Pure Chemical Industries, AAL-107), causes proteins to be resolved both on the basis of size and phosphorylation state. This means that phosphorylated and de-phosphorylated forms of the same protein can be distinguished.
For the study of mRNA decay rates, transcription was inhibited with ActinomycinD, and RNA splicing with Sinefungin, at different time points, in the Matthews lab. rRNA depleted RNA was extracted from each of the samples in the Clayton lab, and sent for deep sequencing at the BioQuant facility in Heidelberg
