Background Information
Function
NeuN, also known as FOX3 or RBFOX3, belongs to a family of tissue-specific splicing regulators and is involved in neural circuitry balance, as well as neurogenesis and synaptogenesis (PMID: 26619789).
Tissue specificity
NeuN is exclusively present in post-mitotic neurons and is absent from neural progenitors, oligodendrocytes, astrocytes, and glia (PMID: 1483388).
Involvement in disease
· NeuN cytoplasmic localization is increased in the neurons of patients with HIV-associated neurocognitive disorders (PMID: 24215932).
Isoforms
There are 4 isoforms of NeuN, migrating in the 45-50 kDa range (PMID: 21747913).
Post-translational modifications
Currently not known.
Cellular localization
NeuN predominantly localizes to the nucleus but can also be present in the cytoplasm. Isoforms of NeuN differ in their cytoplasmic/nucleus localization (PMID: 21747913).

Reviews
What customers say
Most reviewers rate this NeuN antibody highly (average ~4.7/5), praising its strong, specific signal with low background in immunofluorescence across brain sections, neurons, organoids, and cell lines. It also performs well in Western blot and IHC. Dilutions range from 1:50 to 1:1000 depending on application. One reviewer noted reduced specificity in mixed (non-pure) neuronal cultures, suggesting titration is important. Overall, users report clean staining suitable for co-localization studies and reliable performance across multiple sample types.

Ahmad (Verified Customer) (04-29-2026) | Good antibody for IF
|
Víct0r (Verified Customer) (07-24-2025) | In my case, this antibody doesn't seem very specific. It binds to cells that are not neurons. However, in pure neuronal cultures, it works well, although there is a bit of background. I’ve just seen that titrating this reagent is recommended, but in this case, it wasn’t titrated.
 |
Raquel (Verified Customer) (07-12-2024) | Nice and clean staining. Immunofluorescence analysis in cryostat sections of 4% PFA fixed human brain organoid derived from iPSCs using 26975-1-AP NeuN antibody at dilution of 1:250 (under 20x lens). (Magenta: NeuN ; Blue: DAPI)

Manohar (Verified Customer) (03-06-2024) |
|
Damien (Verified Customer) (02-15-2024) | Works well in 2D staining of induced neurons, starting at 14days. Fixed and permeabilized with 3%BSA and 0.1% Triton
|
Monika (Verified Customer) (06-08-2023) | Very specific and strong signal. Used without antigen retrieval. Worked good for both NBT/BCIP-colorimetry and Alexa fluor-fluorescence detection.
|
Russell (Verified Customer) (05-23-2023) | Antigen heat retrieval with Citrate buffer pH 6.0 at 100C for 20 min Permeabilized with 1% TX-100 Blocking Buffer PBST with 5% Donkey Serum
|
Irina (Verified Customer) (11-18-2021) | Good specific neuronal signal. Works nicely for double IF to look at co-localisation with other proteins.
|
David (Verified Customer) (01-13-2020) | Good nuclear localisation, with strong signal and low background.
|
Maxence (Verified Customer) (09-05-2019) | Labeling was neat without any background. Signal was quite strong and stable.
|
Elena (Verified Customer) (07-31-2019) | Good antibody, stained in all cell lines we used it for.
