Anti-NeuN Antibody

Raised in rabbit against the RBFOX3-encoded neuronal nuclear protein, this polyclonal IgG antibody from Antibodies.com targets NeuN, a nuclear marker of post-mitotic neurons used to distinguish mature neuron populations in central and peripheral nervous system tissue. Supplied as 100 µL of unconjugated reagent, the antibody supports western blot and immunohistochemistry workflows on human, mouse, and rat samples, fitting routine labeling studies in developmental neuroscience, neurodegeneration models, and neuronal lineage characterization.

The antibody binds the fox-1 homolog 3 antigen expressed in most neuronal nuclei, enabling nuclear labeling in tissue sections and band detection on western blots of neural lysates. The reagent is used to confirm neuronal differentiation in stem cell-derived cultures, map neuron distribution in lesion models, and benchmark neuronal loss in disease tissue, pairing with HRP- or fluorophore-conjugated secondary antibodies for chromogenic or fluorescence readout.
