摘要:
This invention describes the identification of novel organic dye chemistries that can be used as affinity baits to capture proteins and other biomolecules useful in the fields of medical diagnostics, environmental science, toxicology, and infectious disease. Incorporation of unique affinity dye compounds within hydrogel capture particles improves analyte yield and preanalytical precision, and stabilizes the analyte against degradation, while increasing measurement sensitivity. The particles in this invention can be used for routine clinical testing as well as for discovery of low abundance disease biomarkers. Example hydrogel particles containing new high affinity bait chemistries were used to identify a new set of human serum biomarkers.
