The Neu (Phospho-Tyr1221/Tyr1222) antibody is designed to detect human epidermal growth factor receptor 2 (HER2/ErbB2) when phosphorylated at tyrosine residues 1221 and 1222. HER2. encoded by the ERBB2 gene, is a receptor tyrosine kinase belonging to the EGFR family, which plays a critical role in regulating cell proliferation, survival, and differentiation. Phosphorylation at Tyr1221/1222 occurs in the C-terminal regulatory domain upon receptor activation, typically through dimerization with other HER family members (e.g., HER3). This post-translational modification triggers downstream signaling cascades, including the PI3K/AKT and MAPK pathways, driving oncogenic processes.
Overexpression or hyperactivity of HER2 is strongly associated with aggressive cancers, particularly breast and gastric cancers. The Neu (Phospho-Tyr1221/Tyr1222) antibody serves as a key tool to study HER2 activation status in research and clinical settings. It is widely used in techniques like Western blotting, immunohistochemistry, or immunofluorescence to assess phosphorylation-dependent HER2 signaling in cell lines, tissues, or tumor samples. This antibody also aids in evaluating the efficacy of HER2-targeted therapies (e.g., trastuzumab) and identifying resistance mechanisms. Specificity for phosphorylated epitopes ensures accurate detection of activated HER2. making it valuable for both basic research and translational oncology studies.
