Generation of a rat monoclonal antibody specific for glyoxalase I.

Glyoxalase I (GLO1) is a key enzyme that plays a role in the detoxification of methylglyoxal (MG), a toxic cellular metabolite produced during glycolysis. The present study reports on the preparation and properties of a monoclonal antibody (MAb) directed against mouse GLO1. The antibody was produced by hybridization of mouse myeloma cells with lymph node cells from an immunized rat. The MAb 6F10 specifically recognized GLO1, as evidenced by immunoblotting using a variety of extracts from cultured cells. In immunostaining using MAb 6F10, a diffuse cytoplasmic and nuclear staining pattern was observed. The MAb 6F10 promises to be useful in immunoblotting and immunostaining experiments in various cells and tissues to determine the expression levels of GLO1, as well as to further analyze the biological function of this protein.
