With over 30 years of experience developing and manufacturing recombinant proteins for life science research, our manufacturing and quality standards ensure that our proteins exhibit lot-to-lot consistency, as well as high levels of bioactivity, high purity, and low endotoxin levels.
Many of our proteins are sold as units of activity per vial instead of in units of mass per vial (µg or mg). Each new lot of protein is tested internally using the same bioassay to provide a valid activity comparison between lots. (ED50 is the amount of protein required to elicit a 50% maximum response in the bioassay.) Providing our proteins by activity instead of mass ensures that your results are biologically relevant.
Cytokines and Growth Factors
Cytokines and growth factor products expressed in human, E.coli, and CHO-cells.
Human Cell Expressed (HCE) cytokines closely mimic native human proteins. Interleukin-15, 22, 28A, 28B, and 29 available.
Interferon Decoy Receptor
Viral C12R Interferon Antagonist selectively neutralizes all mouse IFN-Alpha subtypes.
Our IFNs are high purity, provide consistent performance and biological activity, and are suitable for use in a range of research applications.
Human Interferon proteins for Type I, II and III.
Cynomolgus, Rhesus, Feline, Porcine, and Bovine Interferon proteins.
Mouse Interferon Alpha, Beta, and Lambda proteins.
