An integral part of functional proteomics is the study of Total Proteins in order to investigate protein expression patterns and protein interaction among many different tissues. BioChain provides one of the largest selections of Total Protein in the research market that have been isolated from over 300 different tissues and cells. We provide total protein from normal human donors as well as many different disease states. We also provide total protein isolated from other animals as well as customized samples to fit your needs.

Our Total protein is isolated by our proprietary techniques and is stored in protein storage buffer. This product is a useful tool for accelerating gene expression analysis by identifying disease or tumor-specific proteins and genes. Protein Lysates undergo rigorous quality control and protein purification procedures to ensure high quality samples. Lot-to-lot consistency has been established to enable reproducible results.


  • High quality with intact protein structure
  • Decontamination of polysaccharide, proteoglycan, RNase, and genomic DNA
  • Extensive quality control procedures to ensure high quality
  • Documentation of tissues' clinical history is available


  • Western Blot
  • Immunoprecipitation
  • Electrophoresis
  • Enzymatic activity analysis
  • Protein-protein interaction
  • Tissue specific expression identification

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.
