Eosinophil Antibody (BMK-13) Summary

The antibody reacts with the Eosinophil Major Basic Protein antigen.
BMK-13 binds to the 10 kD eosinophil Major Basic Protein (MBP) of both resting and activated eosinophils in cytospins and frozen sections of bronchial and skin biopsies of allergic sites and normal sites and thus can be used as a "pan-eosinophil" marker. The antibody BMK-13 stains in frozen sections of bronchial biopsies from atopic asthmatics, rhinitics and normal non-atopic subjects, substantially higher counts of positive cells when compared to EG1, EG2 and chromotrope 2R. BMK-13 cross-reacts weakly with human basophils, which also contain low level of this protein. It does not cross-react with any other human protein or cell.

Application Notes
This mAb is a very useful tool for clinical and experimental allergy studies. BMK-13 is a pan-eosinophil marker in both frozen sections and paraffin embedded tissues. It stains in bronchial sections 98% of the periphere blood eosinophils. Further, the antibody is most useful for immunohistochemistry on frozen sections is the APAAP method. BMK-13 also binds to eosinophils in paraffin-embedded tissue. A 1:30 dilution in PBS is recommended. Incubation time: 1 hour at RT. Enzymatic pretreatment is necessary. This antibody is suitable for blood smears (cytospins) if fixed with methanol-acetone mixture (1:1, v/v). It is unlikely, without permeabilization, that the BMK-13 is suitable for the flow cytometry because BMK-13 stains intracellular, stored proteins.
