Anti-FKHR (Ab-256) Antibody

This polyclonal antibody from Antibodies.com specifically recognizes the forkhead box transcription factor FOXO1, also known as FKHR, when phosphorylated at residue 256, a regulatory site targeted by the Akt/PKB kinase cascade. The unconjugated rabbit antibody is provided as 100 µl of reagent validated for western blot, immunohistochemistry, and immunofluorescence workflows. Reactivity is established in human, mouse, and rat samples, supporting comparative studies in insulin signaling, metabolic disease models, and tumor biology, where phosphorylation of forkhead box proteins controls nuclear export and target gene activation.
