Extraction of Total Proteins from Rice Plant —BIO-PROTOCOL
This protocol provides an efficient method for preparation of high-quality proteins from rice leaves and grains. The method involves phenol extraction to separate proteins from the non-protein components such as polysaccharides, lipids and phenolic compounds that are commonly enriched in plant tissues. Following isolation, proteins are precipitated with ammonium acetate/methanol and then .
