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), Rrepresents H, a C-Calkyl group, a hydroxy group, an amino group, or a carboxy group. Rrepresents H, a C-Calkyl group, a C-Calkoxy group, a halogen element, NOor N(CH). Rand Reach independently represent H or CH, where Rand Rmay be bonded to each other to form a ring, and in such a case, Rand Rare CH. Herein, 1 represents 1 or 2, m represents 0 or 1, n represents 1, 2, or 3, and Z represents a fluorescent group).
