About circRNA Reagents

Circular RNAs (circRNAs) from GenCefe Biotech — covalently closed RNA rings with no free 5′/3′ ends. With no open end for exonucleases to attack, circRNA resists degradation and sustains protein expression longer than a linear mRNA of the same sequence. The panel encodes fluorescent and luminescent reporters (EGFP, mCherry, firefly luciferase) in standard and high-purity (HQ) grades. For research use only (RUO).

circRNA vs mRNA vs siRNA vs plasmid DNA

circRNA is built for durable, integration-free expression — a more stable alternative to linear mRNA.

How to read this: use circRNA when you want longer expression than linear mRNA while avoiding integration. For a fast, short pulse of protein, the mRNA reagents are simpler; to silence a gene, use the pre-designed siRNA library.
