Description: Affinity capture with low flow chromatography and high-resolution mass spectrometry (AC-LCMS) is a hybrid method for bioanalysis of pharmacodynamic markers and protein/peptide therapeutics. It achieves low LLOQs, accuracy, precision, broad linear dynamic range, and robustness. We present two case studies: 1) TL1A biomarker analysis in human serum with LLOQ of 40 pg/mL using hybrid AC-LCMS, and 2) TMT chemistry for bioanalysis of known mAb therapeutics spiked in serum.
