  • Function
    Involved in neurogenesis. Also required for the specification of a common precursor of the 4 pancreatic endocrine cell types.
  • Involvement in disease
    Defects in NEUROG3 are the cause of diarrhea type 4 (DIAR4) [MIM:610370]. DIAR4 is a characterized by severe, life-threatening watery diarrhea associated with generalized malabsorption and a paucity of enteroendocrine cells.

  • Anti-Neurogenin3 antibody (ab38548) at 1/1000 dilution + Mouse liver tissue lysate

    HRP goat anti-rabbit (H+L) at 1/5000 dilution

    Predicted band size : 23 kDa
    Observed band size : 23 kDa

    Incubation time was overnight at 4°C.

  • ab38548 (4µg/ml) staining Neurogenin-3 in human jejunum using an automated system (DAKO Autostainer Plus). Using this protocol there is strong nuclear staining.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human large intestine tissue labelling Neurogenin3 with ab38548. A peroxidase-conjugated anti-rabbit IgG was used as the secondary antibody, followed by DAB staining.

  • ab38548 staining Neurogenin3 in mouse psotnatal day 8 testes tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 4$ paraformaldehyde and blocked with 5% BSA for 1 hour at 25°C; antigen retrieval was by heat mediation in 0.1M citric acid/sodium citrate. Samples were incubated with primary antibody (1/200) for 1 hour at 25°C. A FITC-conjugated donkey anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.

Thank you for contacting us.

We have incubated the sections with primary antibody for 20 minutes at room temperature. However we recommend the users should incubate the antibody for at least 4 hours or overnight in case the staining is faint...
