Protein mass spectrometry ppt
WebbMass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of charged particles. It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical structures of molecules, such as peptides and other chemical compounds 3 PRINCIPLE WebbTo identify potential ER biomarkers, we profiled the rat plasma glycoproteome after treatment with vehicle or 17β-estradiol (E2) or an ERα-selective agonist PPT by …
