From a lectin library containing plural types of lectins or an arbitrary mass of lectins containing plural types of lectins, lectins needed for analyzing sugar chains are selected to thereby construct a lectin sublibrary. Using the lectin sublibrary thus constructed, cells having sugar chains are identified. Moreover an indication , method whereby cells can be conveniently identified is provided.
