Anti-ErbB2/HER2 (T1242) Antibody

This rabbit-derived polyclonal reagent targets a defined T1242 epitope of ErbB2 (also known as HER2) and is applicable to both Western blot and immunohistochemistry workflows, with reactivity confirmed in human, mouse, and rat samples. Supplied as a 50 µl vial at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide at approximately pH 7.2, the unconjugated antibody is ready to aliquot into working stocks for repeated immunoblotting or staining sessions.

Antibodies.com formulates this reagent for immunodetection of the ErbB2 receptor tyrosine kinase, an EGFR family member that drives proliferation and differentiation signaling. Researchers apply the polyclonal antibody when profiling receptor levels in HER2-driven oncology models and in normal tissue surveys across human, mouse, and rat systems, leveraging its cross-species reactivity for comparative studies.

The PBS-azide formulation supports bench-stable handling under routine use; aliquotting the 1 mg/ml stock limits loss across repeated freeze-thaw cycles during extended projects and preserves the polyclonal pool for both Western blot membranes and immunohistochemistry sections.
