Anti-NeuN Antibody

Raised in rabbit against the RBFOX3 nuclear RNA-binding protein, this polyclonal IgG reagent from Antibodies.com serves as a marker of post-mitotic, mature neurons throughout the central and peripheral nervous system. Supplied as an unconjugated 200 µl liquid aliquot, the antibody is validated for Western blot and immunohistochemistry on samples derived from human, mouse, and rat tissues. In immunoblotting it recognizes the RBFOX3 target, and in immunohistochemistry it selectively labels neuronal nuclei in fixed brain, spinal cord, and dorsal root ganglion sections, supporting studies of neuronal differentiation, neurodegeneration, and lineage tracing. Researchers apply the reagent to identify mature neurons in mixed primary cultures, to quantify neuron numbers in injury and disease models, and to distinguish neurons from surrounding glia in tissue sections. Store the vial at -20°C and divide into single-use aliquots to minimize freeze-thaw cycles and preserve long-term activity across many experiments.
