Our Abpromise guarantee covers the use of ab65319 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 81 kDa).|
FunctionMediates tyrosine nitration of secondary granule proteins in mature resting eosinophils. Shows significant inhibitory activity towards Mycobacterium tuberculosis H37Rv by inducing bacterial fragmentation and lysis.
Involvement in diseaseDefects in EPX are the cause of eosinophil peroxidase deficiency (EPD) [MIM:261500]. EPD is an autosomal recessive defect where anomalous eosinophils are characterized by nuclear hypersegmentation, hypogranulation, and negative peroxidase and phospholipid staining.
Sequence similaritiesBelongs to the peroxidase family. XPO subfamily.
Cellular localizationCytoplasmic granule. Cytoplasmic granules of eosinophils.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 81 kDa
Observed band size: 70 kDa why is the actual band size different from the predicted?
Additional bands at: 15 kDa, 55 kDa (possible cleavage fragment). We are unsure as to the identity of these extra bands.
Exposure time: 20 minutes
We hypothesise that this antibody is detecting the EPX monomer (~70kDa) and the cleaved heavy chain(55kDa). Abcam welcomes feedback from customers working on this protein and would appreciate any comments regarding this product and the data presented above.
