Rapid, Label-Free Protein and Peptide Quantification with Sub-ppm LOQ Using A-TEEM™ Spectroscopy

This application note demonstrates how A-TEEM delivers accurate, highly linear, and reproducible protein quantification with sub-ppm limits of detection and quantification. In addition to sensitive concentration measurements, A-TEEM simultaneously generates rich spectral fingerprints, providing valuable structural and compositional insight from a single rapid, label-free analysis.
