Abstract: In order to prepare the monoclonal antibody against 1,5‐anhydro‐glucitol (1), it was conjugated with bovine serum albumin (BSA), human serum albumin (HSA) or chicken lysozyme (CL) using succinate or β‐alanine succinate as a spacer to produce individual antigen conjugates. The number of hapten contained in each antigen conjugate was determined by matrix‐assisted laser desorption/ionization tof mass (MALDI‐tof‐MS) spectrometry. The formation of monoclonal antibody (MAb) was also discussed.
