10.14.26 -- Better Translatability. Higher Capping. Ultra-low dsRNA.

When Capping Efficiency Isn't Enough: Rethinking AG-Capped IVT Workflows

A strong capping number can mask real problems: cap analog cost, dsRNA burden, and yield that swings with template and UTR design. See how AG-capped workflows hold up under process development pressure.

 

T7 Compatibility Is Not The Same As T7 Performance

T7-promoter workflows are easy to adopt, but familiarity can mask gaps in yield, dsRNA formation, capping flexibility, and translatability that surface only as a program reaches process development and scale-up.

Data Review: Primrose Bio Launches Prima RNApols® Cap AG And Prima RNApols® 7 Pro

RNA polymerase choice influences IVT output quality, affecting capping efficiency, double-stranded RNA levels, and purity across AU-capped, self-amplifying, and T7 promoter-based workflows, with distinct enzymes suited to different template and capping priorities.

 

dsRNA Formation: How RNA Polymerase Choice Can Reduce It

T7 polymerase makes a lot of dsRNA during IVT, which drives up purification costs. Non-T7 alternatives tell a different story, and the data makes a compelling case for reconsidering your enzyme selection.

 

Strategies To Reduce mRNA Manufacturing Costs

Cap analog, DNA template, and RNA polymerase drive most of the raw material spend in mRNA production. See exactly how far you can cut each one before yield suffers.

 

SOLUTIONS

Match The Prima RNApols Enzyme To Your IVT Workflow

Aligning polymerase selection with template design and capping strategy shapes yield, dsRNA formation, and reagent cost at every stage. Find the enzyme built for the workflow you are actually running.
