For mRNA drug substance to be safe and efficacious it must be highly capped. Yet measuring the capping efficiency of RNA is a technical challenge. Here we present several case studies of using InDevR’s VaxArray instrument as a high-throughput capping efficiency and integrity assay in partnership with HPLC-based capping efficiency methods. This combination allows streamlining of workflows to facilitate process development around enzymatic and co-transcriptional capping. Projects can then easily move from R&D to research-grade manufacturing, with clear paths into GMP manufacturing.

5’CapQ Assay: Simplify Measurement of mRNA Attributes
The 5′ cap and poly(A) tail elements of mRNA are essential for protein expression and mRNA stability. Waiting for the mRNA analysis of concentration, intactness, and purity from a central laboratory or outsourced partner slows down mRNA vaccine development.
In just 90 minutes, the 5’CapQ Assay is a simple, direct measurement of capped and tailed mRNA. This assay works by capturing the mRNA molecules via the 5’ cap and labeling the molecules on the poly(A) tail, enabling quantification of only the complete intact mRNA molecules. RNA molecules that lack a 5’ cap or poly(A) tail are not measured in the 5’CapQ Assay, leading to a single test for quantifying your mRNA.
- Develop Vaccines Faster – Consolidate your mRNA capping and intactness testing into 1 assay that can be completed in less than two hours.
- Analyze at Your Benchtop – Reduce testing bottlenecks by bringing mRNA analytics to your facility.
- Simplify Workflow Process – compatible with LNP formulations eliminating the need for laborious extraction procedures.
