Sterogene Bioseparations is a manufacturer of chromatography resins for the purification of biomolecules used in every step from crude feed streams to final polishing steps.  We offer a wide range of resins and custom services as described on our website.

Sterogene has designed and manufactured products for the downstream purification of biotherapeutics, for more than 25 years. We supply some of the world’s leading biopharmaceutical companies and many academic research laboratories with chromatography resins.  We have cGMP manufacturing and we are ISO 9001 certified.

We are industry leaders in the area of capturing proteins and other molecules from crude feed streams using packed bed columns with our pioneering and patented Direct Capture™ technology using our CellThru™ resins.  We also excel in the final polishing steps with our line of endotoxin-removal Etox resins. We offer specialty resins and ligand development services including ligand design using our advanced in silico bioinformatics capabilities.

We produce many custom products. If you do not find what you need in our catalog of products, please feel free to contact us.  We look forward to working with you and developing the most cost- and time-efficient solutions for your downstream purification or contaminant removal needs.
