  • FunctionPhotoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal.
  • Tissue specificityRod shaped photoreceptor cells which mediates vision in dim light.
  • Involvement in diseaseRetinitis pigmentosa 4
    Night blindness, congenital stationary, autosomal dominant 1
  • Sequence similaritiesBelongs to the G-protein coupled receptor 1 family. Opsin subfamily.
  • Post-translational
    Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region.
    Contains one covalently linked retinal chromophore.
  • Cellular localizationMembrane. Synthesized in the inner segment (IS) of rod photoreceptor cells before vectorial transport to the rod outer segment (OS) photosensory cilia.

  • ab3267 staining Rhodopsin in Rat eyeball tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 2% BSA for 20 minutes at 25°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/500 in 1% BSA in PBS) for 1 hours at 25°C. A HRP-conjugated Goat anti-mouse IgG polyclonal undiluted was used as the secondary antibody.
    Rods and cones of retinal outter granular cells were stained positively for rhodopsin. In normal conditions, synthesized rhodopsin is predominatly stored in the cellular projects, not in the cell bodies.

  • Overlay histogram showing Y79 cells stained with ab3267 (red line). The cells were fixed with 4% paraformaldehyde (10 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 (ab3267, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Y79 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Thank you for your enquiry.

I can confirm that recent trials did not show any influence on product performance after an additional freeze thaw cycle and so we advise customers that they can store this antibody frozen at -20oC now.

Thank you for your enquiry. It may indeed be possible to use antibodies in IHC-Fr (frozen sections) when they are already working in IHC-P. This is likely as the fact they work in IHC-P means they have the capacity to recognise the antigen in its na...

Thank you for your enquiry. The antibody ab3267 has been tested in immunocytochemistry in IF in IMR-5 cells, unfortunately we do not have information about the dilution used but since the antibody worked at 4ug /ml for 30 min at RT in paraffin sections...
