Our Abpromise guarantee covers the use of ab183399 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml.

1 μg/mL of ab183399 was sufficient for detection of rhodopsin in 10μg of rat eye lysate by colorimetric immunoblot analysis.

ICC/IF Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration.
IHC-Fr Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
IP Use at 4 µg/mg of lysate.


  • Function

    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.
  • Tissue specificity

    Rod shaped photoreceptor cells which mediates vision in dim light.
  • Involvement in disease

    Retinitis pigmentosa 4
    Night blindness, congenital stationary, autosomal dominant 1
  • Sequence similarities

    Belongs 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 localization

    Membrane. Synthesized in the inner segment (IS) of rod photoreceptor cells before vectorial transport to the rod outer segment (OS) photosensory cilia.
