The HER2 (Phospho-Tyr877) antibody is a specialized tool used to detect the phosphorylated form of HER2 (Human Epidermal Growth Factor Receptor 2) at tyrosine residue 877. HER2. a member of the EGFR tyrosine kinase family, plays a critical role in cell proliferation, survival, and differentiation. Its overexpression or hyperactivation is linked to aggressive cancers, particularly breast and gastric cancers. Phosphorylation at specific tyrosine residues, such as Tyr877. is essential for HER2 activation and downstream signaling via pathways like MAPK and PI3K/AKT. This post-translational modification typically occurs upon receptor dimerization and ligand binding, promoting oncogenic signaling.
The HER2 (Phospho-Tyr877) antibody enables researchers to study the activation status of HER2 in cancer cells, providing insights into tumor progression and therapeutic responses. It is widely used in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to assess phosphorylation levels in cell lines, xenografts, or clinical samples. Detection of phosphorylated HER2 can help evaluate the efficacy of targeted therapies (e.g., tyrosine kinase inhibitors or monoclonal antibodies like trastuzumab) and identify resistance mechanisms. Additionally, this antibody supports research into HER2-driven signaling crosstalk and its role in metastasis. Its specificity for the phosphorylated epitope ensures accurate monitoring of HER2 activation dynamics in both basic and translational cancer studies.
