Our Abpromise guarantee covers the use of ab19306 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 0.1 - 0.2 µg/ml. Detects a band of approximately 53,85 kDa. Endogenous melanopsin is expressed at low levels making it difficult to detect. We recommend running a positive control and conducting experiments on samples overexpressing melanopsin protein.
IHC-P Use at an assay dependent concentration.
ICC/IF Use a concentration of 10 µg/ml.


  • Function
    Photoreceptor required for regulation of circadian rhythm. Contributes to pupillar reflex and other non-image forming responses to light. May be able to isomerize covalently bound all-trans retinal back to 11-cis retinal.
  • Tissue specificity
    Eye. Expression is restricted within the ganglion and amacrine cell layers of the retina.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
  • Cellular localization
    Cell membrane. Found in soma, dendrites and proximal part of axons of certain retinal ganglion cells.
