The High-Salt Solution for Precipitation (Plant) may be used for high-quality RNA purification from plant samples and to enable polysaccharide and proteoglycan removal. The reagent is typically used to remove any remaining polysaccharides in the plant homogenate sample following RNA preparation. High-purity total RNA can be obtained by adding the High-Salt Solution for Precipitation (Plant) reagent during the isopropanol precipitation step of plant RNA extraction.
