Method for the Detection of Antigen Presentation

摘要

The present invention pertains to a method for detecting antigen presentation via antigen presenting molecules such as major histocompatibility complex (MHC) class I or II. The invention deploys a first binding agent specific for the antigen epitope and a second binding agent specific for the antigen presenting molecule. The binding agents of the invention are coupled to proximity probes which upon antigen presentation elicit a detectable signal. The method of the invention allows detecting antigen presentation via MHC in-vitro and in a tissue sample in-situ. Thus the method of the present invention finds application as a new diagnostic tool, for example in the diagnosis of various diseases such as infectious diseases, immunological disorders, in particular autoimmune diseases, and proliferative disorders such as cancer.
