Anti-FGFR1 (phospho Y766) Antibody

Raised against the tyrosine 766 autophosphorylation site of human fibroblast growth factor receptor 1, this rabbit polyclonal antibody from Antibodies.com selectively detects the activated, phosphorylated form of FGFR1 rather than total receptor levels. Supplied as 100 µl of unconjugated IgG, the reagent is validated for Western blot in human samples, where phospho-Y766 recognition lets researchers track receptor activation and downstream PLCγ/MAPK signaling. The polyclonal format improves detection of the modified epitope across denatured, reduced lysates prepared for SDS-PAGE and western transfer. Aliquot the vial upon arrival and store frozen at -20°C, limiting freeze-thaw cycles and protecting from light to preserve phospho-specific activity. Typical working dilutions fall in the 1:500 to 1:2000 range for western blot, depending on the abundance of activated FGFR1 in the sample, and the unconjugated format is compatible with HRP-, biotin-, or fluorophore-labeled secondary reagents chosen by the researcher.
