Title: Immunenzymometrisches verfahren zur quantitativen bestimmung des isoenzyms bb der humanen glykogenphosphorylase b
Inventor: NOLL FRANZ
IPC: G01N33/573
Filed: 1988-07-12
Abstract: Die Erfindung betrifft ein immunenzymometrisches Verfahren zur quantitativen Bestimmung des Isoenzyms BB der humanen Glykogenphosphorylase b (EC 2.4.1.1.) fuer die medizinische Diagnostik von Herzmuskelerkrankungen. Das erfindungsgemaesse Verfahren ist dadurch gekennzeichnet, dass zwei monoklonale Antikoerper (mAk) gegen das Isoenzym BB der humanen Glykogenphosphorylase b verwendet werden, wobei diese zwei am Enzymmolekuel entfernt voneinander gelegene antigene Determinanten erkennen und binden. Einer der mAk wird an die feste Phase gebunden und mit der das Enzym in unbekannter Menge enthaltenden Probe in Reaktion gebracht. Anschliessend wird nach Bindung des zweiten mAk, der an ein Markerenzym gekoppelt ist, das gebundene Isoenzym BB der humanen Glykogenphosphorylase b ueber die Enzymaktivitaet des Markerenzyms quantitativ bestimmt. Das erfindungsgemaesse Testsystem erlaubt die quantitative Bestimmung des Isoenzyms BB der humanen Glykogenphosphorylase b mit hoher Empfindlichkeit selbst in Gegenwart hoher Konzentrationen des Isoenzyms MM, da alle eingesetzten mAk keine Kreuzreaktivitaet mit dem Isoenzym MM zeigen.
