PARTICLE LABELING REAGENT, PARTICLE DYEING METHOD, AND MICROSCOPIC SYSTEM

Abstract:

To provide a particle labeling reagent having low luminescent characteristics and improved water solubility. Provided is a particle labeling reagent containing a compound represented by the following general formula (I-1) or (I-2). ##STR00001## (In the above general formula (I-1), p represents an integer of 1 to 3. In the above general formula (I-1), M represents a hydrogen atom or a mono- to tri-valent metal atom. In the above general formula (I-1), L.sup.1 represents a single bond or a (p+1)-valent group. In the above general formulas (I-1) and (I-2), L.sup.2 and L.sup.3 each independently represent a hydrogen atom or a photodegradable protecting group, and L.sup.2 and L.sup.3 may be the same or different. Provided that at least one of L.sup.2 and L.sup.3 represents a photodegradable protecting group. In the above general formula (I-2), L.sup.4 represents a monovalent group.)
