摘要： The present invention addresses the problem of providing a novel method for classifying cancer cells by an analysis method in which measurement of the activity of two types of protein kinase is used. Cancer cells are newly classified and drug sensitivity is predicted on the basis of the ratio of the activity of two types of protein kinase derived from the same sample.
