    Bead milling will lyse most Gram positive and Gram negative bacteria including mycobacteria. It can be performed by adding glass beads and lysis solution to a bacterial cell pellet and milling for a few minutes. It is possible to lyse some Gram negative bacteria by sonication in lysis solution alone.

  • Redefining the Translational Status of 80S Monosomes Cell

    To preserve polysome integrity we lysed cells by vortexing with glass beads rather than ball milling as ball milling tends to shear polysomes and thereby artificially increase the monosome fraction. We also excluded detergent (e.g. Triton X-100) as it led to excessive foaming and poor cell lysis.
