Lectins for analyzing sugar chains and method of using the same

摘要

It is expected that lectins of a needed number of types appropriately corresponding the variation of sugar chains, if available, are highly useful as tools for analyzing various sugar chains. 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 sub-library. Using the lectin sub-library thus constructed, cells having sugar chains are identified. Moreover, an indication method whereby cells can be conveniently identified is provided.
