KIT AND METHOD FOR SELECTING CANCER PATIENTS FOR WHOM ADMINISTRATION OF ANTIBODY PHARMACEUTICAL FOR HER2 PROTEINS, WHICH ARE THERAPEUTIC TARGET MOLECULES, IS EFFECTIVE

摘要

The present invention provides a kit and a method for selecting cancer patients for whom the administration of an antibody pharmaceutical for HER2 proteins, which are therapeutic target molecules, is effective. The kit contains a lateral flow immunoassay test strip that has a structure in which there are connected, in sequence from the upstream side in the direction of sample flow, a sample pad where a sample is added, a conjugate pad that holds first anti-HER2 protein antibodies, a membrane that has a region where second anti-HER2 protein antibodies and antibodies that bind to the first anti-HER2 protein antibodies are immobilized, and an absorbent pad, wherein an antibody pharmaceutical for HER2 proteins, which are therapeutic target molecules, is used for either of the first anti-HER2 protein antibodies and the second anti-HER2 protein antibodies. The method according to the present invention includes a step for detecting HER2 proteins in the cancer tissue of a patient by lateral flow immunoassay using this test strip.
