Anti-FGF-4 Antibody

Raised in rabbit as a polyclonal preparation, this unconjugated antibody recognizes fibroblast growth factor 4 (FGF-4), a member of the FGF family originally identified through its transforming activity in human gastric carcinoma and also known as HST-1 or KFGF. FGF-4 functions as a heparin-binding mitogen that signals through FGFR1-FGFR4 receptors and contributes to embryonic patterning, limb bud outgrowth, tooth germ development, and maintenance of pluripotent stem cells. The reagent is supplied as 100 µl of ready-to-use antiserum suitable for Western blot detection of endogenous FGF-4 protein and for ELISA-based quantification, with demonstrated reactivity against human, mouse, and rat samples. Researchers studying developmental signaling, stem cell self-renewal, or oncogenic pathways where FGF-4 has been implicated can use this Antibodies.com reagent to probe expression in cell lysates, tissue homogenates, or conditioned media. The unconjugated format allows flexibility in choosing secondary detection systems and fluorophore or enzyme pairings to match existing Western blot and ELISA workflows.
