Antibody was affinity purified using an epitope specific to HdmX/MDM4 phosphorylated at Ser 403 immobilized on solid support. The epitope recognized by A300-392A maps to a region surrounding phosphorylated Ser 403 of human ortholog of mouse double minute 4 using the numbering given in entry NP_002384.2 (GeneID 4194).Immunoglobulin concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.
