Plant Membrane Protein Extraction Kit is a high yield membrane protein extraction kit, based on chemical rather than detergent. It can extract membrane proteins from various plants, and can be used for crude protein preparation and membrane protein preparation. The extraction process is simple and convenient. The kit contains a mixture of protease inhibitors and phosphatase inhibitor mixture, preventing the protei degradation by protease, providing a guarantee for extracting high quality protein. Extracted Proteins using this kit has natural activity and can be used for a variety of downstream experiments.
