Researchers studying protein localization and trafficking now have a convenient tool: the MinuteTM Water-soluble and Water-Insoluble Protein Fractionation Kit for cells/tissues. This unique product allows for the rapid and efficient separation of these two key fractions from cells/tissues, microorganisms and plant tissues, providing enriched and easily detectable protein samples for downstream applications like western blotting, ELISA and immunoprecipitation. Water soluble fraction contains mainly cytosolic proteins and water-insoluble fraction contains mainly insoluble membranous structures such as plasma membrane, nuclear membrane and organelles. The kit offers researchers a novel and simple approach for understanding protein function and movement within the cellular landscape. If a protein target is known to be localized in water-soluble or water-insoluble fraction, the kit will facilitate detection, isolation and purification of the target protein by enrich corresponding fractions.
