Abstract

A method for lysing prokaryotic or eukaryotic cells, or for simultaneous lysis of both, which includes at least three of the following: a mass of active, small-diameter beads corresponding to 50% or less than a mass of active, larger-diameter beads, and/or a total mass of lysing beads (consisting of a single type of bead or a mixture of smaller and larger beads) corresponding to between 50 and 100% of the total mass of the processed biological sample, and/or a lysis time of from 10 to 20 minutes, and/or seven or less non-lysing glass beads to drive the movement of the lysing beads, and/or from five to fifteen non-lysing iron beads to drive the movement of the lysing beads, depending on whether sonication, mechanical vortex centrifugation or magnetic vortex centrifugation is used.
