Anti-FGFR1 (phospho-Y154) Antibody

This rabbit polyclonal reagent from Antibodies.com targets fibroblast growth factor receptor 1 phosphorylated at tyrosine 154 (FGFR1 phospho-Y154), a modification linked to receptor dimerization and downstream MAPK signaling. Raised in rabbit and purified as an unconjugated IgG preparation at 1 mg/ml in phosphate buffered saline (pH 7.2) with 0.05% sodium azide, the antibody is validated for Western blot detection across human, mouse, and rat samples. Each vial contains 100 µl of ready-to-dilute stock; aliquot upon arrival to limit repeated freeze-thaw cycles and refrigerate to preserve phospho-specific binding activity. The polyclonal format offers broader epitope coverage than monoclonal alternatives, an advantage when surveying FGFR1 activation states in cell lysates derived from fibroblast, epithelial, or neuronal backgrounds.
