Our ssDNA
Synthesis Services

We make ultrapure sequence-verified ssDNA with unprecedented length, scale and complexity, to advance gene therapies and gene-based technologies. Use our ssDNA as your HDR donor template for CRISPR, or as a non-viral vector in cell and gene therapies.

Our ssDNA Capabilities

1. Gene scale length (up to 10 Kb)

2. Any sequence complexity including high CG content, strong secondary structures and repeats

3. No harsh chemicals, thanks to in vitro enzymatic DNA synthesis

4. Minimal cytotoxicity

5. Precise knock-in with very limited off-target events

6. Multi-milligram scale

7. Free life-time template storage for faster and more cost-effective re-orders
