Abstract: Compositions and methods for controlling or eliminating isotope effects during fractionation of chemically equivalent but isotopically distinct compounds. Isotope coding agents contain heavy isotopes other than deuterium. The invention facilitates intelligent data acquisiton. After sample fractionation, isotope abundance ratios are calculated using mass spectrometry, and analytes of interest are identified in real time.
Abstract: This invention discloses a novel substrate and assay for the TAP enzyme. In addition novel DNA, proteins and peptides from genes and proteins associated with bacterial teichoic acid biosynthetic pathways, specifically the rodC gene and proteins and variations thereof are disclosed.
