A sensitive method for determining the proteolytic activity in culture filtrates


, : A sensitive method for determining the proteolytic activity in culture filtrates. Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie 254(2): 229-233

A new method for the quantitative determination of low proteinase activities in culture filtrates or other complex protein-containing substrates has been developed. The method is based on the inactivation of streptokinase which is monitored by following the reduction of fibrinolysis. In a time interval ranging from 1 to 500 min, the half-life of streptokinase activity is directly proportional to proteinase concentration. The enzymatic reactions are not interfered with by either other proteins or coloured substances.
