A comparison of branched DNA and reverse transcriptase quantitative polymerase chain reaction methodologies for quantitation of lipid nanoparticle encapsulated mRNA.

Messenger RNA (mRNA)-based therapeutics have emerged as a promising modality for various clinical applications, necessitating robust methods for mRNA quantification. This biodistribution study compares the performance of branched DNA and reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) assays for measuring lipid nanoparticle-encapsulated mRNA. Following intravenous administration of nascent peptide imaging luciferase mRNA (1 mg/kg) to rats, mRNA levels in various tissues and serum were quantified using both assays.
