About
Ansa Biotechnologies is a synthetic DNA synthesis company developing enzymatic DNA writing technology to overcome the length and quality limitations of chemical DNA synthesis. Founded in 2021 and headquartered in Emeryville, California, Ansa uses engineered terminal deoxynucleotidyl transferase (TdT) enzymes rather than phosphoramidite chemistry to build DNA strands, enabling synthesis of longer sequences with higher fidelity and fewer toxic reagents. The company emerged from research at UC Berkeley and Lawrence Berkeley National Laboratory.
