Easy lysis of bacterial cells to release recombinant proteins The FastPROTEIN™ Blue Matrix, also known as Lysing Matrix B, is used with any FastPrep® Instrument to reproducibly lyse gram positive and gram negative bacterial cells within 40 seconds. A brief protocol is provided to allow for the maximum flexibility in lysis and purification methods. Rapid release of recombinant protein saves valuable time during optimization of expression. Information from up to 24 different induction variables can be quickly obtained after one 40 second FastPrep® run followed by electrophoresis. Once your protein of interest is expressed and identified, the active proteins released by the unique motion of the FastPrep® Instruments can be recovered from the lysate by a wide range of protein-specific techniques.
