Anti-FES Antibody

Produced in rabbit as a polyclonal reagent, this unconjugated primary antibody targets the FES (Feline Sarcoma Oncogene) non-receptor protein tyrosine kinase, encoded by the FES gene and involved in myeloid cell differentiation, cytokine-driven signaling, and cytoskeletal reorganization. Supplied by Antibodies.com at 100 µL per vial, the antibody is validated for western blot and immunohistochemistry on human, mouse, and rat samples, supporting studies of FES expression in hematopoietic lineages, immune cell regulation, and signaling pathways downstream of receptor tyrosine kinases. The host species is rabbit and the reagent is unconjugated, allowing flexible selection of secondary labels for chromogenic or fluorescence-based detection in fixed tissue sections and immunoblot membranes. For storage, aliquot the antibody on receipt and place vials at -20°C in a frost-free freezer to limit freeze-thaw cycles and preserve activity over time. The polyclonal format provides recognition of multiple epitopes across the FES protein, useful when probing full-length kinase in tissues where alternative isoform expression is under investigation. Researchers working on macrophage activation, neutrophil motility, or viral oncogene homology commonly pair this reagent with appropriate lysis buffers and phosphatase inhibitors to capture phosphorylation-dependent events. Each lot is affinity-purified to reduce non-specific background in IHC applications involving formalin-fixed, paraffin-embedded sections, and the unconjugated format allows integration into existing streptavidin-biotin or polymer-HRP detection workflows.
