6.2.8. Product analysis.

The various newly synthesized components can be separated and analysed using methods as determined by the nature of the precursor label. When radioactive labelling is involved, the major compounds or classes of compounds can be separated by a number of techniques depending on the nature of products, for example HPLC separation with radioactive detection. Other options include thin-layer chromatography (TLC) separation followed by phosphor imager detection (Katzav-Gozansky et al., 2000) as described in section For stable isotopes, GC-MS or LC-MS using single ion monitoring can be used (Tsfadia et al., 2008). Below, we take the example of Dufour’s and Mandibular glands for the description of the analysis of exocrine glands products (after Katzav-Gozansky et al., 1997).
