Anti-EGFR (E687) Antibody

This rabbit polyclonal antibody from Antibodies.com targets the Epidermal Growth Factor Receptor (EGFR), with the E687 epitope designation marking the immunogen region used for rabbit immunization. It is supplied as 50 µl of liquid at 1 mg/ml in phosphate buffered saline containing 15 mM sodium azide at approximately pH 7.2, and is unconjugated for flexible pairing with a wide range of secondary detection reagents. The reagent is validated for Western blot, immunohistochemistry, and immunofluorescence workflows on Human, Mouse, and Rat samples, supporting research in cancer biology, receptor tyrosine kinase signaling, and cell-surface receptor mapping across tissue sections and cultured cell models. The polyclonal format offers recognition of multiple epitopes on EGFR, which can improve detection robustness in samples where a single monoclonal reagent may yield weaker or more variable signals. To preserve binding activity, aliquot the antibody upon arrival and store at -20°C, avoiding repeated freeze-thaw cycles, and thaw vials on ice before each use. This research-use-only primary antibody is well suited to signaling studies, tumor biology investigations, and characterization of EGFR expression in normal versus diseased specimens.
