Minute™ Plant Microsomal Membrane Extraction Kit

Isolation of microsomal membranes from plant tissues is a common procedure. The microsomal fraction of plant cell lysate is the focus of interest in many plant research projects and is believed to be enriched for plasma membranes, endoplasmic reticulum, Golgi apparatus, vacuolar membranes, and other components of a membrane system. Traditional methods for microsomal fraction isolation involve differential pelleting, where centrifugation steps are required for membrane fractions. Microsomal fraction isolation usually requires a large amount of starting material and has tedious ultracentrifugation steps. MM-018 offers a simple, fast, and user-friendly approach for microsomal membrane extraction with a small amount of starting material. During the procedures, water-soluble cytosolic proteins are removed, and water-insoluble microsomal fraction, especially plasma membrane fraction, is extracted with optimized buffers in a tabletop microcentrifuge. Native microsomal proteins can be isolated from plant tissue in about one hour without ultracentrifugation. The protein yield is in the range of 100-200 µg/sample.
