Compound, cellular vesicle staining agent, and method of fluorescent staining for cellular vesicles

Abstract

An object is to provide a novel compound that specifically conjugates with intracellular and/or extracellular vesicles, a cellular vesicle staining agent, and a method of fluorescent staining for cellular vesicles. The object can be achieved by a compound expressed by the following Formula (1). [Formula 1] (In Formula (1), R1 represents H, a C1-C6 alkyl group, a hydroxy group, an amino group, or a carboxy group. R2 represents H, a C1-C18 alkyl group, a C1-C18 alkoxy group, a halogen element, NO2 or N(CH3)2. R3 and R4 each independently represent H or CH3, where R3 and R4 may be bonded to each other to form a ring, and in such a case, R3 and R4 are CH2. Herein, 1 represents 1 or 2, m represents 0 or 1, n represents 1, 2, or 3, and Z represents a fluorescent group).
