IGHG1 (heavy chain) mouse monoclonal antibody, clone IG266, Purified

Applications ELISA: Use Antibody without BSA for Coating.
Flow Cytometry: 0.5-1 μg/106 cells.
Immunofluorescence: 0.5-1 μg/ml.
Western Blot: 0.5-1 μg/ml.
Immunoprecipitation: 0.5-1 μg/500 μg protein lysate.
Immunohistochemistry on Frozen and Formalin-Fixed Paraffin Sections: 0.5-1 μg/ml for 30 minutes at RT.
Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
Positive Control: 293T, Raji or hPBL cells. Tonsil or Spleen.

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.
