  • Function
    Probable transcription factor which may play a role in the regulation of specific gene expression within a subset of neuronal lineages. May play a role in determining or maintaining the identities of a small subset of visual system neurons.
  • Tissue specificity
    Brain. Seems to be specific to the retina. Present in the developing brain, spinal cord and eye.
  • Sequence similarities
    Belongs to the POU transcription factor family. Class-4 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.
  • Developmental stage
    Expression peaks early in embryogenesis (day 13.5) and is undetectable 14 days after birth.

  • Overlay histogram showing SH-SY5Y cells stained with unpurified ab81213 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab81213, 1/50 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab81213).

  • Flow Cytometry analysis of SH-SY5Y (Human neuroblastoma epithelial cell) cells labeling BRN3A with purified ab81213 at 1:100 dilution (red). Cells were fixed with 4% Paraformaldehyde. A Goat anti rabbit IgG (Alexa Fluor ® 488) secondary antibody was used at 1:2000 dilution. Isotype control - Rabbit monoclonal IgG (Black). Unlabeled control - Cell without incubation with primary antibody and secondary antibody (Blue).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab81213).
