Purification of total RNA from bacteria using the RNeasy® Mini Kit - (EN)

Up to 1 x 10⁹ bacteria are disrupted and homogenized by bead-milling in a guanidine-thiocyanate-containing lysis buffer. After addition of ethanol, the sample is loaded onto an RNeasy Mini spin column. Total RNA binds to the RNeasy silica-membrane, contaminants are efficiently washed away, and high-quality RNA is eluted in RNase-free water.
