Non-isotopic labelling

{
  "id": "MLC-T-CHM-008030",
  "term": "Non-isotopic labelling",
  "field": "Chemistry",
  "definition": "Labelling in which attaching the label gives a product whose chemical composition differs from that of the starting compound, as when a fluorescent group, an enzyme or a radioiodine atom is coupled to a molecule that did not contain it. It contrasts with isotopic labelling, where an atom is replaced by another isotope of the same element and the chemical composition is unchanged.",
