Simultaneous quantification of siRNA antisense and sense strands by hybrid liquid chromatography-mass spectrometry.

Bioanalysis

January 2025

Bioanalysis Discovery & Development Sciences, Johnson & Johnson, Spring House, PA, USA.

Background: Most oligonucleotide bioanalytical assays currently only quantify the pharmacologically-active antisense strand, though there have been recent efforts to simultaneously quantify the sense strand using hybridization ELISA or solid phase extraction LC-MS. Hybrid LC-MS, which offers both high sensitivity and specificity unlike the currently used platforms, has not been applied to quantify both siRNA strands simultaneously.

Materials & Methods: A hybrid LC-MS assay utilizing LNA capture probes was developed and applied to quantify both strands of a 21-mer lipid-conjugated siRNA (SIR-3) using tandem mass spectrometry (MS/MS).
