NTP Building Blocks

An enzymatic platform that harnesses nature’s catalyst to create better RNA — pure, scalable, and endlessly customizable

ezRNA™

Template-free synthesis to install site-specific modifications

Full Length Product

Ligation of blockmers enables a fully enzymatic synthesis for any length RNA

Blockmers + Ligation

Modality-agnostic enhancements for any existing designs

Hybrid Synthesis

Modifications

In addition to known therapeutically relevant modifications, we’ve incorporated numerous others, including novel and natural, spanning the stability, conjugation and delivery space

Base

Standard and non-standard nucleobases cab be incorporated with the ezRNA™ platform. Bases with fluorophores, alkyl groups, halogens, conjugation handles, and more are also compatible

2’ Sugar

Essential for siRNA therapeutics, the platform can incorporate all standard 2’ modifications including 2’OH, 2’H, 2’OMe and 2’F. Other halogens, locked nucleic acids, and more are also tolerated on the 2’

3’ Sugar

The flexibility of the platform provides access to 3′- modifications including dideoxy, click handles, and chain terminators.

Backbone

The ezRNA™ platform can install both standard, phosphorothioated, boronated backbones and more

We work with partners

Across discovery and CMC to deliver RNA at the scale and quality required for advanced therapeutics
