Recombinant Proteins

Recombinant proteins are a foundational tool for life science research. It used to be common to express proteins in-house, but most researchers can now buy high-quality recombinant proteins that support their research for a fraction of the cost and with fast turnaround.

Aviva Systems Biology has been providing high-quality protein products to the scientific community for over 10 years. In addition to our diverse catalog and semi-custom recombinant protein products, we also offer comprehensive custom recombinant protein expression and production services to meet a variety of research needs.
