Cytokines & Proteins
Quality & Performance View Products
R&D Systems is the world’s premiere source of recombinant proteins, including cytokines, growth factors and enzymes. Extensive quality control produces industry leading bioactivity and lot-to-lot consistency that instills confidence in results and ensures reproducibility.
At R&D Systems, quality and performance is the number one priority.
R&D Systems’ experience and dedication to protein development and manufacturing is unmatched in the life science industry.
The R&D Systems® Quality Advantage- For new proteins multiple lots are created, all with matching specifications. This ensures that there will be no problem matching original lots in the future.
- Each new lot is tested side-by-side with previous lots for purity, biological potency, and endotoxin level.
- Proprietary methods for accurate protein folding ensure biologically relevant proteins
- R&D systems uses over 900 validated bioassays to evaluate recombinant proteins bioactivity
- Bioactivity is measured experimentally with the appropriate biological system.
- Each new production lot of protein is assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay. The endotoxin specification is an industry-leading <0.1 EU/ug.
- Each protein is tested to rule out microbial contamination using direct plating and broth dilution, according to guidelines from the United States Pharmacopeia (USP).
- N-terminal amino acid sequence analysis is performed for each recombinant protein to verify the protein produced matches the sequence expected
- Recombinant proteins are formulated for best stability and are lyophilized from a sterile filtered solution. They are available without or with a carrier protein, usually bovine serum albumin (BSA) at 50 mg/mg of protein.
- Recombinant enzymes are in solution and ready to use
