Breaking Down mRNA Capping Efficiency with High-Resolution IP-RP LC

Evaluating 5′ capping efficiency is a critical quality attribute in therapeutic mRNA manufacturing, directly impacting translation efficiency and transcript stability. However, separating structurally similar capped, partially capped, and uncapped species differing by just a single nucleotide remains a significant chromatographic challenge.

Our latest Application Note highlights an optimized ion-pair reversed-phase liquid chromatography (IP-RP LC) method designed to tackle this complexity.

𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗕𝗶𝗼𝗶𝗻𝗲𝗿𝘁 𝗛𝗮𝗿𝗱𝘄𝗮𝗿𝗲: Utilizing the widepore YMC Accura Triart Bio C18 column to eliminate unwanted secondary interactions and deliver robust, reproducible results.

𝗦𝗲𝗮𝗺𝗹𝗲𝘀𝘀 𝗟𝗖-𝗠𝗦 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻: Successfully applied to LC-MS workflows using mass-extracted ion chromatograms (MICs) to definitively differentiate between Cap-0, Cap-1, and critical uncapped impurities.
