Anti-FOXO3A (phospho-S253) Antibody

Manufactured by Bioworld Technology and distributed through the Antibodies.com catalogue, this recombinant rabbit monoclonal antibody is raised against FOXO3A when phosphorylated at serine 253, a key regulatory site within the forkhead domain of this transcription factor. Each vial is supplied as a 50 µl liquid formulation in 1× TBS (pH 7.4) containing 1% BSA and 40% glycerol, with 0.05% sodium azide added as preservative, and the antibody is Protein A affinity purified to remove non-specific background. The reagent is unconjugated, enabling flexible secondary detection in western blot and immunohistochemistry workflows across Human, Mouse, and Rat samples, with an observed molecular weight near 71 and 97 kDa in reduced SDS-PAGE. Specificity is restricted to endogenous FOXO3A only in its phosphorylated state, supporting studies of apoptosis regulation, cellular differentiation, metabolism, and survival pathways where the FoxO subfamily is implicated. The product is intended for research use only and is not approved for diagnostic or therapeutic applications.
