Recombinant Proteins

RS Synthesis provides a comprehensive range of high quality recombinant proteins, and expression systems for custom recombinant production, including bacteria, yeast, baculovirus infected insect cells, and mammalian cells. We offer a full spectrum of protein purification methods, including Tag, Flag Tag, or His Tag options to facilitate purifications of both soluble and insoluble proteins. Purifications without tags available as well. Purities as high as >99% available. The majority of our proteins are manufactured under cGMP conditions resulting in high purity, indisputable bio-activity, and low endotoxin levels.

Our proteins are ideal for all research, animal studies, and diagnostic applications. Each protein comes with a detailed CoA, including SDS-Page. Additional QC documentation provided upon request. We specialize in bulk manufacturing (1mg to multi-gram) of recombinant proteins, including therapeutic variations, with or without additives. For those seeking the fastest, most affordable options, we also provide outstanding intact protein expression and purification (without any tag) in E.coli. Additional services include:

Gene Cloning • Fermentation • Protein Purification • Lyophilization
