Conjugation Unconjugated

Human IgG4 mouse monoclonal antibody, clone MRQ-44, Purified

Applications Immunohistochemistry on Frozen and Formalin-Fixed, Paraffin-Embedded Sections: 1/100-1/500. 
Preparation and Pretreatment:
1. Cut 3-4 μm section of formalin-fixed paraffin-embedded tissue and place on positively charged slides; dry overnight at 58°C.
2. Deparaffinize, rehydrate, and epitope retrieve; the preferred method is the use of Heat Induced Epitope Retrieval (HIER) techniques in conjunction with a pressure cooker. The preferred method allows for simultaneous deparaffinization, rehydration, and epitope retrieval. Upon completion, rinse with 5 changes of distilled or deionized water.
3. If using HRP detection system, place slides in peroxide block for 10 minutes; rinse. If using AP detection system, omit this step.
Positive Control: Tonsil.
Reactivities Human
