Anti-NeuN Antibody - Identical to Thermo (PA5-37407)

Sourced through AFMS and originally developed by Antibodies.com, this primary antibody is a rabbit polyclonal reagent raised against the neuronal nuclear marker NeuN (RBFOX3) and manufactured identically to Thermo Fisher's PA5-37407 reference product. The description on the supplier page reads simply "Rabbit polyclonal antibody to NeuN", and the reagent is supplied as an unconjugated, affinity-purified liquid in two formats — 50 µL and 100 µL — at a working concentration of 1.0 mg/mL. The formulation is a phosphate-buffered saline (without Mg²⁺ or Ca²⁺) at pH 7.4, containing 150 mM NaCl, 0.02% sodium azide and 50% glycerol, while the immunogen used for affinity purification is a recombinant protein corresponding to human NeuN. The host is rabbit, the isotype is IgG and the clonality is polyclonal, providing broad multi-epitope coverage of the target. Validated applications listed by Antibodies.com are Western blot (WB) and immunohistochemistry (IHC), and the antibody has been confirmed to react with human, mouse and rat samples, making it well suited as a pan-neuronal marker across standard neuroscience models and human tissue specimens. For shipping and storage, vials leave the St. Louis, MO facility in 6–9 business days on cold packs at 4 °C; upon receipt the product should be aliquoted and stored at -20 °C, with repeated freeze/thaw cycles avoided to preserve antibody activity.
