ABSTRACT:
Active carboxylic acid ester groups are coupled on the surfaces of microspheres so as to reduce protocols for microsphere processing, control side reactions, and stably preserve beads containing active carboxylic acid ester groups. Further, microspheres labeled with at least one fluorescent dye cage in the microspheres, and the microspheres are preserved in lower alcohol.
