Thermo Scientific Subcellular Protein Fractionation Kit for Tissue includes all reagents and tissue strainers required to perform cell fractionation and enrichment of proteins from five different cellular compartments within 2 hours.

Features of Subcellular Protein Fractionation Kit for Tissue:

Optimized—formulations and protocols specific for fractionation of tissue
Complete—obtain cytoplasmic, membrane, soluble nuclear, chromatin-bound and cytoskeletal protein fractions from a single kit
Time efficient—extract functional protein fractions without ultracentrifugation in approx. 2 hours
Convenient—unique tissue strainer allows rapid removal of tissue debris
Compatible—use extracts for downstream applications such as protein assays, Western blotting, protein assays, electrophoretic mobility shift assays, reporter-gene and enzyme-activity assays.
Versatile—extract proteins from a variety of tissue types, including liver, heart, brain, kidney, lung and spleen

• Obtain cytoplasmic, soluble nuclear, chromatin-bound, membrane and cytoskeletal proteins from the same tissue sample
• Profile disease-state versus normal tissues for proteins from the cytoplasm, nucleus, membrane and cytoskeleton
• Study protein translocation in tissues

Subcellular Protein Fractionation Kit for Tissue includes a unique 250 µM tissue strainer to facilitate rapid separation of cell suspension from tissue debris after homogenization. The optimized reagents enable subsequent stepwise extraction of cytoplasmic, membrane, nuclear soluble, chromatin-bound and cytoskeletal proteins from the recovered cells with less than 15% cross-contamination.

Subcellular Protein Fractionation Kit for Tissue contains four extraction buffers, tissue strainers, a stabilized nuclease and Thermo Scientific Halt Protease Inhibitor Cocktail. Each kit has sufficient reagents and tissue strainers to process and fractionate 25 tissue samples up to 200 mg each. The tissue is homogenized in the first reagent, which causes selective membrane permeabilization, releasing soluble cytoplasmic contents. This homogenate is transferred to a tissue strainer to remove excess tissue debris. The second reagent dissolves plasma, mitochondria and ER-golgi membranes, but does not solubilize the nuclear membranes. After recovering intact nuclei by centrifugation, a third reagent yields the soluble nuclear extract. An additional nuclear extraction with micrococcal nuclease is performed to release chromatin-bound nuclear proteins. The recovered insoluble pellet is then extracted with the final reagent to isolate cytoskeletal proteins.
