EZ – Retriever® IR System is a microwave-based antigen retrieval pre-treatment system invented by BioGenex. It is used for dewaxing, rehydration and antigen retrieval of formalin fixed paraffin embedded (FFPE) tissue sections to enhance exposure of antigenic epitopes. This system not only resolves the issues of inconsistency due to different types of antigen retrieval methods by applying different maximum microwave power levels, solution volumes and heating time but also facilitates the standardization of dewaxing and antigen protocols for high quality and reproducible staining.
