Novus provides 42,000+ highly purified control peptides and proteins to ensure reliable results and reproducibility. We offer bioactive proteins suitable for an array of functional assays. Novus has both native proteins isolated from serum, cells, and tissue sources, and purified recombinant proteins. Our catalog includes lyophilized ProDots proteins that are perfect for cell culture. Many of our products are available in Animal-Free and Carrier-Free formats, ideal for in vivo applications. We also carry blocking peptides and proteins to use as quality controls to confirm antibody specificity. Browse our extensive catalog of products and sort by target, research application, species reactivity, rating review, and citations to find the exact product you need. Novus also offers bulk and custom protein production services to meet your research needs.
