Built with Precision DNA Synthesis

Our rapid, scalable DNA synthesis platform enables us to quickly generate defined synthetic libraries. We convert your parental antibody to the closest germline sequence and comprehensively explore the mutational space with unprecedented efficiency.

End-to-End Support for Antibody Development

Our DNA synthesis capabilities also enable us to offer high-throughput conversion from scFv, Fab, or VHH formats to full-length IgG. Our team of antibody experts leverages their collective 50 years of experience to streamline development, with biochemical, biophysical, and functional screening of any TAO antibodies.

What Scientists Have to Say

Twist is the only synthetic DNA provider who can deliver the quantity and quality of DNA we need for our projects rapidly. We are working with them not only as a vendor for synthetic genes and antibodies, but have expanded our relationship to leverage the Twist Biopharma capabilities, which we believe complement our antibody discovery efforts.
