The invention relates to monoclonal antibodies (MAbs) against neuropeptide Y (NPY). 4 MAbs which are directed against the following regions of NPY have been found: MAb NPY 04 against amino-acid sequence 1 - 12 of NPY MAb NPY 02 against amino-acid sequence 8 - 18 of NPY MAb NPY 03 against amino-acid sequence 27 - 36 of NPY MAb NPY 05 against amino-acid sequence 32 - 36 of NPY<*> <*>including N terminus. The invention also relates to the use of the MAbs NPY 02-NPY 05, in particular as diagnostic aid for determining human NPY (h NPY). <IMAGE>
