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