Bacterial RNA isolation with one hour centrifugation in a table-top ultracentrifuge.
A procedure for the rapid preparation of cesium-chloride purified RNA from E. coli and the cyanobacterium Synechococcus sp. PCC7942 is described. Cells are lysed in modified sucrose, Triton X-100, EDTA, Tris buffer with phenol/chloroform. The cleared lysate is extracted further with phenol/chloroform and RNA is peleted by centrifugation through a 5.7 M CsCl cushion. High quality RNA can be prepared in three hours using this procedure.
