METHODS OF DETERMINIG ENZYME ACTIVITY IN PRESERVED CELL SAMPLES

摘要

A method of determining enzyme activity in preserved cells is disclosed. The method comprises: (a) contacting preserved cells with a substrate for an enzyme under conditions wherein the enzyme catalyzes a reaction of the cells with the substrate, so as to generate a product capable of producing an electrical signal; and (b) measuring a level of the electrical signal, wherein a level of the electrical signal correlates with enzyme activity. Uses of same for diagnosing diseases are also disclosed.
