Ansa launches 50 kb sequence-perfect clonal DNA, the longest synthetic DNA sold commercially

Ansa Biotechnologies/Enzymatic long-DNA synthesis

After an early-access programme with more than 20 institutions, Ansa launched clonal DNA constructs up to 50,000 bases, verified by long-read sequencing and delivered in under 25 business days. Constructs made by conventional chemical synthesis rarely exceed 10 kb, so whole gene circuits, large gene-therapy payloads and complex vectors can now be ordered rather than built by hand.

• Price from $0.28 per base pair, falling with length.
• Early users include the Allen Institute's Seattle Hub for Synthetic Biology and Applied StemCell.
• Covered by Ansa's on-time guarantee.
