Custom Protein Development

Your Protein, Our Expertise

Recombinant protein technologies play a vital role in academic research and drug discovery. We believe that full length proteins are vital for activity, physiological relevancy, and structure. For over 30 years R&D Systems has produced gold-standard proteins. Ensure your critical reagents perform with R&D Systems custom protein production.

What to Expect

High Purity
High Purity

R&D Systems manufactures >95% of our proteins in house. With complete control over all quality testing, we are able to generate proteins to meet industry-leading purity specifications.

Biological Activity
Biological Activity

Proprietary methods for accurate protein folding ensure biologically relevant proteins and >900 validated bioassays, activity can be evaluated for most protein targets.

Lot-to-lot Consistency
Lot-to-lot Consistency

Multiple lots are created for R&D Systems proteins, all with matching specifications. Each new lot is tested side-by-side with previous lots to ensure unmatched consistency.

Low Endotoxin
Low Endotoxin

Each new production lot of protein is assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay. Our standard endotoxin specification is an industry-leading <0.1 EU/ug.

Beyond the Catalog:

Your protein may already be available! We have thousands of proteins in the freezer that are used as immunogens to generate antibodies or have yet to be released. Proteins in our freezer may have different tags or utilize a different expression system than the ones found in our catalog.

We recognize that researchers have unique needs. If you don’t find what you are looking for on our website, please contact us and find out if we have your protein of interest.

Features:

  • Manufactured by R&D Systems
  • Thousands of proteins available
  • Same Quality testing as retail proteins
  • Test samples are available
  • Unique proteins, tags, and sources
  • Bypass the need for custom development
