Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IH
Catalog #M2110
ApplicationsSuitable for use in Immunohistochemistry, Western Blot and ELISA. Other applications not tested.
Recommended DilutionImmunohistochemistry (fresh frozen): Tissues were sectioned (6um), dried for 1 hour at RT and fixed in 1:1 solution of methanol and acetone. Sections were air dried for 1 hour. Sections may be stored wrapped in aluminium foil at -70°C until used.
Immunohistochemistry (Paraffin): 4% PFA (3hr) should be used for skin biopsies. 5um sections are dewaxed and rehydrated with water. A proteinase treatment of 0.1% trypsin for 15 minutes in water should be performed prior to blocking and antibody staining.
Note: The antibody reacts better in frozen tissues than in paraffin embedded tissues.
Western Blot: Purified normal human eosinophils were treated with digitonin (5mg/ml) for 10 minutes before boiling in sample buffer. Ran on a 15% SDS-PAGE. Purified MBP migrates at ~14kD, with typical human samples ranging from 10-16kD.
Optimal dilutions to be determined by the researcher.
SourceTissue culture supernatant

ImmunogenMajor Basic Protein
SpecificityRecognizes human eosinophil major basic protein independent of the stages of eosinophil activation and can be regarded as a pan-eosinophil marker. Recognizes the 28.3kD secreted pro-form of MBP (Pregnancy Associated MBP) found in the placenta and serum of pregnant women as well as the 13.8kD mature form of the protein which is found in the matrix of the eosinophil large specific granual. Species Crossreactivity: Does not crossreact with equine, mouse or rat MBP.
