ABSTRACT:
Methods and reagents for labeling molecules of interest in a plurality of samples, and then combining and selecting labeled molecules away from unlabeled molecules for use in simultaneous co-assaying analysis. The reagents comprise labeling means of distinguishable radioactive isotopes which remain with the labeled molecules. Additionally, the reagents also comprise selection means which can be affinity tags, beads, or immobilized surface which may remain or be cleaved off through cleavable linkers. A set of labeling reagent can be used to label a plurality of samples, combine them before or after selecting/enriching for labeled molecules and co-assay together for reliable comparison. This invention has many applications in comparing and panning for differentially abundant molecules or differential modification of molecules for proteomics, glycomics, phospho-proteomics, metabolomics, epi-genomics . . . studies.
