Isotope labeling is a kind of popular technique used to track the target molecule by a metabolic pathway, a reaction, or a cell. The principle of tracking the passage of an isotope is to replace the specific atoms of the target molecule by their isotope because the difference between the isotope and the original atoms is relatively easily detective in the following experiment. Thus the sequence the isotopic atom followed in the reaction or the cell's metabolic pathway can be determined by the position of the isotopes in products. The nuclides used in isotopic labeling may be stable nuclides or radionuclides. In the latter case, the labeling is called radiolabeling.
Identification of glycosylated proteins requires that they are separated, either physically or spectrometrically, from complex mixtures that contain both unglycosylated and heterogeneously glycosylated proteins. In newer methods, labels can be introduced either by the exploitation of glycoprotein-specific reactions or by using the cell’s biosynthetic machinery. After chemical tagging, covalent modification with a highly selective probe enables glycoprotein isolation, which can be followed by mass spectrometry analysis. Isotope-labeled glycoproteins can be identified and quantified by their mass spectrometry signatures. Currently, the most effective strategies for glycoprotein identification combine these methods, using chemical tagging for isolation and isotope tagging for mass spectrometry analysis.
