Protein Isolation

FracPRO™ Protein Fractionation Kit
Ultracentrifuge-Independent Method Separate Four Subcellular Protein Fractions.

FracPRO™ Protein Fractionation Kit is a product with highly specialized fractionation buffers which can target specific subcellular compartment and with ultracentrifuge-independent method to separate four subcellular protein fractions, including nuclear, cytosol, membrane/organelle, and cytoskeletal fractions in a detergent-based procedure. It can simultaneously preserve the structural integrity of the proteins and can directly be used in SDS-PAGE, enzyme analyses, gel mobility shift assays and other procedures.
