for the rapid screening of specific post-translational modifications antibody-based methods are very well suited and applicable without demanding expenditure. Here we describe the immunochemical detection of the O-glycosidically linked cytosolic N-acetylglucosamine modification of proteins, which has attracted increasing interest in the last years. Two different monoclonal antibodies were used in enzyme-linked immunosorbent assays (ELISA), Western blots of 1- and 2- dimension (1D and 2D) separated proteins and immunohistochemical analysis of tissue sections. Slight differences in the recognition of this post-translational epitope by the 2 antibodies are observed and will be discussed.
