Read article Method Development and Validation of a Biomarker Analog by Hybrid LC-MS/MS with Two-Dimensional Chromatography in Human Matrices

Discover in this poster presented by Ryan Darling at WRIB 2026 on how a validated hybrid immunoaffinity LC–MS/MS method using a surrogate peptide and 2D chromatography enables selective, sub-ng/mL quantitation of a KLK1 analog in human plasma, overcoming LBA limitations caused by near-identical endogenous KLK1.
