Anti-FGFR2/CD332 Antibody

Fibroblast growth factor receptor 2 (FGFR2/CD332) is a transmembrane tyrosine kinase central to epithelial morphogenesis, skeletal development, and oncogenic signaling in gastric and breast cancers. The monoclonal antibody from Antibodies.com recognizes an epitope on human and mouse FGFR2, supplied unconjugated at 100 µl in 1% BSA, 40% glycerol, TBS pH 7.4, with 0.05% sodium azide as preservative. Validated for western blot, immunocytochemistry, and immunohistochemistry workflows, this mouse IgG1 clone supports reproducible detection of receptor expression and downstream pathway activation across lysate, fixed-cell, and paraffin tissue-section preparations. Common research uses include mapping FGFR2b versus FGFR2c isoform expression, profiling tumor biopsies for receptor amplification, and characterizing resistance mechanisms to tyrosine kinase inhibitors. Storage at 4°C covers routine bench handling; aliquoting and freezing at -20°C preserves antibody activity across repeated experiments and avoids excessive freeze-thaw cycles on the glycerol-stabilized stock.
