Enzyme quality

Built for clean, reliable in vitro transcription.

All ArtPure™ polymerases are purified through our proprietary ArtPure™ process — yielding a >99% pure, animal origin-free product with no added enzyme inhibitors.

No contaminating hydrolases

Free of proteinases, RNases and DNases that degrade template or transcript.

>99% purity

Evaluated by SDS-PAGE on every batch, with a Certificate of Analysis shipped alongside the product.

No added inhibitors

Clean formulation supports flexible downstream use without unexpected interference.

Room-temperature option

Lyophilized T7 ships without cold chain — reducing cost, complexity and environmental footprint.
