METHODS FOR THE DETECTION AND QUANTITATION OF THE P95 COMPONENT OF HER2/NEU (ERBB2)

摘要

The present disclosure relates generally to methods for the detection and quantitation of the p95 component of HER2/neu (ERbB2). Such methods may comprise assaying the biological sample for expression of HER2 ICD; assaying the biological sample for expression of a HER2 ECD; quantitating an expressed amount of the HER2 ICD and an expressed amount of the HER2 ECD in the biological sample; and determining the amount of p95 expressed in the biological sample based on a difference between the expressed amount of the HER2 ICD and the expressed amount of the HER2 ECD. The methods of the present disclosure may be used to predict whether a subject will be responsive to a receptor tyrosine kinase inhibitor and/or may be used to select subjects for inclusion/exclusion in a clinical trial.
