Peripheral blood granulocytes are classified into neutrophils, basophils and eosinophils according to the staining characteristics of their cytoplasmic granules. Granule proteins are released by physiologic and pharmacologic stimuli and play important roles in both normal and pathological host immune responses. Eosinophil major basic protein and eosinophil peroxidase (EPX)are granule proteins specific to the eosinophil. This MAb stains eosinophils only and does not stain other peripheral blood cells, including platelets, neutrophils, monocytes, lymphocytes or red blood cells. Human EPX gene product can form a tetramer of two light chains and two heavy chains. Other peroxidase family members include myeloperoxidase (MPO), lactoperoxidase (LPO), and thyroid peroxidase (TPO).

The concentration stated for each application is a general starting point.Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.

Human eosinophils from a patient with hypereosinophilic syndrome were used as the immunogen for this Eosinophil peroxidase antibody.

Store the Eosinophil peroxidase antibody at 2-8°C.
