General description

ProteoPrep® Membrane Extraction Kit reagents utilize a powerful detergents for higher loading and resolution of proteins in 2D gels. Protein Extraction Reagent Types 3 and 4 are optimized for proteomic studies. Extraction reagents 3 and 4 are ideal for protein extraction prior to isoelectric focusing and 2D electrophoresis. This kit also includes reagents for the reduction and alkylation of disulfide bonds. The ProteoPrep® Membrane Extraction Kit was designed through a collaboration of Proteome Systems and Sigma research scientists.


ProteoPrep® Membrane Extraction Kit is designed to prepare highly enriched membrane protein solutions from many types of cells. The final protein solution are suitable for 2D gel electrophoresis.

Features and Benefits

  • Innovative detergent preparations - Improved solubility allows for higher protein loads and greater visibility of low abundance proteins in 2D gels.
  • Two pre-mixed solubilization solutions - Removes interfereing non-membrane proteins prior to extractions, resulting in uncluttered 2D arrays.
  • Pre-measured reducing & alkylating reagents - Easy-to-use reagents provide improved IEF resolution.

Fetuin-A is a known inhibitor of vascular calcification in vitro. In arteries with calcification, there is increased immunostaining for fetuin-A. However, vascular smooth muscle cells (VSMC) do not synthesize fetuin-A, suggesting fetuin-A may be endocytosed to exert its inhibitory effects.
