STABLE LABELING MEDIUM USABLE IN BIOLOGICAL EXPERIMENTS

摘要

It is intended to provide particles for labeling which can be quickly detected in a minor amount, in particular, can be detected even in severe environment in the case of detecting a biomolecule such as an antigen or an antibody, and can be observed with the naked eye. This object can be achieved by providing a labeling agent containing a dye and a polymer. The above object can be achieved by providing particles with the use of a structural color dye (for example, a pearl pigment containing mica and a metal oxide) as the dye, though it is a nonlimiting example.
