Membrane Protein

Introduction to Membrane Protein

Membrane proteins are an integral part of molecular biology research. These proteins interact with biological membranes and are the target of over 50% of all modern medicinal drugs. Membrane proteins perform a variety of functions that are crucial to the survival of organisms such as relaying signals, transport, and cell adhesion. Additionally, approximately 20 – 30 % of genes within a genome encode membrane proteins.

At BioChain, we’ve prepared membrane proteins from a large variety of documented quality tissues that are ready-to-use for genetic testing and analysis. Our tissue membranes are prepared from whole tissue homogenates and are of high-quality. Distinction of quality is ensured by consistent patterns on SDS-PAGE analysis, as well as by storage in protease inhibitor cocktail buffer.


  • Membrane protein isolated from diseased and normal tissues and from tumor cell lines
  • Available from human, monkey and rat tissues
  • Decontamination of polysaccharide, proteoglycan, RNase, and genomic DNA
  • Extensive quality control procedures to ensure high quality
  • Documentation of tissues' clinical history is available
  • Applications

  • Western Blot (10 µg to 20 µg per lane is recommended for a mini gel)
  • Immunoprecipitation
  • Electrophoresis
  • Enzymatic activity analysis
  • Protein-protein interaction
  • Tissue specific expression
  • Quality Control

  • Protein lysate is verified on SDS-PAGE analysis as a consistent pattern.
  • Protein lysate is positively confirmed by Western Blot using specific biomarker: GAPDH for total protein, cytoplasmic and universal total protein; Histone for nuclear protein; Na/K ATPase for membrane protein; Vimentin for cytoskeleton protein.
