  • A rapid chemical method for lysing

    Jul 15, 2011Protein extraction is a frequent procedure in biological research. For preparation of plant cell extracts, plant materials usually have to be ground and homogenized to physically break the robust cell wall, but this step is laborious and timeconsuming when a large number of samples are handled at once. We developed a chemical method for lysing Arabidopsis cells without grinding.
