A collection of reactive mass markers, characterized in that each mass marker in the set has the following structure: X (*)n -LM (*)m ; wherein X is a mass marker part, and L is a cleavable linker , M is the mass normalization part, * is the isotope mass adjustment part, and n and m are 0 or greater integers, so that: the mass markers contained in each marker in the set have a common mass and each marker in the set Each marker has a unique total mass, or each marker in the set contains a mass marker portion that has a unique mass and each marker in the set has a common total mass. |
