Thermo Fisher's Q-Exactive HF mass spectrometry platform, complemented by multiple LC-MS systems from Waters, Dionex and Shimadzu. The advanced quadrupole technology (AQT) within the system improves precursor ion selection and transmission, enabling more accurate quantification of low-abundance analytes in complex clinical sample matrices. The sophisticated data-independent acquisition (DIA) and parallel reaction monitoring (PRM) techniques deliver the qualitative confidence and quantitative reproducibility required for clinical services, supporting a wide range of quantitative proteomics services including TMT, label-free, DIA and PRM.

Proteint collaborates with its allied company Immune Tech (USA) on antibody development for protein biomarkers, translating mass spectrometry research into clinical applications in the form of ELISA kits and Luminex bead-based kits.
