4-AMINO-3-CYANO-1,2,5,6-TETRAH

Two Efficient Methods for the Conjugation of Smooth-Form Lipopolysaccharides with Probes Bearing Hydrazine or Amino Groups. II. LPS Activation with a

This chapter presents a conjugation method for coupling probes bearing hydrazine or primary amino groups to a lipopolysaccharide (LPS). LPS is modified by the activation of the hydroxyl groups present in its O-antigen moiety with 1-cyano
