Title:
QUALITATIVE AND QUANTITATIVE ANALYTICAL METHOD FOR ANALYZING THE ACTIVITY TYPE OF AN ENZYME THAT IS ACTIVATED BY PROTEOLYSIS
Document Type and Number:
WIPO Patent Application WO/2011/149272
Kind Code:
A2
Abstract:
The present invention relates to a qualitative and quantitative analytical method for analyzing the activity type of an enzyme that is activated by proteolysis. The method of the present invention is advantageous in that the activity type of an enzyme present in a specimen is analyzed using an enzyme activity inhibitor and a binder to enable the analysis to be performed in a quicker and more accurate manner as compared to enzyme-activity analysis methods using a simple binder (for example, an antibody). The method of the present invention can enable the analysis of the activity type of an enzyme present in a specimen in a simple manner using less equipment than enzyme-activity analysis methods using a simple binder. The method of the present invention involves simultaneously using the inhibitor and the binder in analyzing the activity type of a target enzyme or an enzyme to enable quick and specific analysis, and high-throughput drug screening can be performed at a high speed due to the above-described characteristics of the method of the present invention. In addition, the method of the present invention can be applied to point-of-care testing (POCT) for the clinical monitoring of the effects and dosage of a drug in a drug administration target (for example, an animal or human).
