Protein Services

Protein Production

We have produced thousands of proteins from >50 species, many not yet listed in our catalog. Your protein of interest may be available immediately or a custom protein can be synthesized from gene cloning to active protein.

Protein Development

Intended Use Driven Manufacturing

Develop a new recombinant protein under the stringent Good Manufacturing Practice (GMP) and Animal-Free quality requirements necessary for use as ex vivo cell therapy reagents or ancillary proteins. Or convert an existing R&D Systems RUO protein to meet your intended use.

GMP Protein Services

In Vitro Modification

Small to large scale protein conjugation with highly QC tested end material. Conjugate proteins to one of the many fluorophores available, biotin, PEG, or utilize other chemical labels to create a product that fits your experimental needs.
