Using quantitative mass spectrometry to search for proteins that contained these stable isotope labels, researchers were able to determine the cell of origin of both intracellular and secreted proteins identified in multicellular culture. (sciencedaily.com)
They used an analytical technique called quantitative mass spectrometry to identify mitochondrial inner membrane proteins which are reduced in cells without OXA. (sciencedaily.com)
He and co-author Steven Gygi turned to state - of - the - art quantitative mass spectrometry techniques to show that the human hormone uses a rare signal ATA (start codon) to initiate its production (translation) rather than the usual ATG. (sciencedaily.com)
