WB: Y79 and WERI whole cell lysates.
IHC-P: Rat normal eye tissue.
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
pH: 7.40 Preservative: 0.02% Sodium azide Constituent: PBS Note: Batches of this product that have a concentration < 1mg/ml may have BSA added as a stabilising agent. If you would like information about the formulation of a specific lot, please contact our scientific support team who will be happy to help.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 48 kDa (predicted molecular weight: 39 kDa).
Use a concentration of 0.5 µg/ml.
The optimal concentration will need to be determined. 0.5ug/mL gave a good result with a polymer-HRP secondary antibody reagent.
Photoreceptor 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.
Rod shaped photoreceptor cells which mediates vision in dim light.
Involvement in disease
Retinitis pigmentosa 4 Night blindness, congenital stationary, autosomal dominant 1
Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region. Contains one covalently linked retinal chromophore.
Membrane. Synthesized in the inner segment (IS) of rod photoreceptor cells before vectorial transport to the rod outer segment (OS) photosensory cilia.
IHC image of Rhodopsin staining in Rat normal eye formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab112576, 0.5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

The predicted molecular weight of Rhodopsin is 39 kDa (SwissProt), however we expect to observe a banding pattern around 48 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
