Thermo Fisher Scientific offers a broad selection of Invitrogen concanavalin A (Con A) conjugates, including Alexa Flour and Alexa Flour Plus conjugates. Concanavalin A selectively binds to alpha-mannopyranosyl and alpha-glucopyranosyl residues. In neutral and alkaline solutions, concanavalin A exists as a tetramer with a molecular weight of approximately 104,000 Daltons. In acidic solutions (pH below 5.0), concanavalin A exists as a dimer. Conjugated concanavalin A has been used in variety of applications, including immunofluorescence (IF), immunohistochemistry (IHC), and flow cytometry (FC).
