RNA Size Is Only Part of IVT RNA QC

Agarose gel electrophoresis can help determine whether an RNA sample appears near the expected transcript size, but it does not quantitatively measure residual double-stranded RNA.

dsRNA can arise as a byproduct during in vitro transcription and therefore represents a separate analytical question from RNA size and integrity.

RNA LADDER

Size & Integrity

Is the transcript approximately the expected size?

dsRNA ELISA

Impurity Analysis

How much residual dsRNA is present in the sample?

J2-Based Quantitative Sandwich ELISA

The assay uses an anti-dsRNA monoclonal antibody to capture dsRNA, followed by HRP-conjugated anti-dsRNA detection.

1. dsRNA Sample
2. Capture by Anti-dsRNA Antibody
3. HRP-Conjugated Detection Antibody
4. OD450 Measurement & Standard Curve

Applications

IVT mRNA
Quantitative comparison of residual dsRNA in IVT samples.
saRNA Research
Complementary impurity analysis for long self-amplifying RNA workflows.
Purification Development
Compare dsRNA levels before and after purification steps.
Process Optimization
Compare experimental IVT or purification conditions.

A Practical Use Case: Before vs After Purification

IVT Reaction
Pre-purification sample
Purified RNA
Post-purification sample

Measuring both samples can help researchers compare relative dsRNA levels and evaluate the effect of purification or process changes.
