Product DescriptionMouse anti-Rhodopsin Monoclonal Antibody (Unconjugated), suitable for WB, IHC-Frozen.
Application DetailsWestern blotting (1:5,000) and Immunohistochemistry (1:1,000). Due to the highly hydrophobic nature of rhodopsin, avoid boiling samples in SDS-PAGE sample buffer for rhodopsin analysis by Western Blotting, as this will result in extensive aggregation of the rhodopsin protein and appearance of high molecular weight bands. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundPhotoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth (By similarity). Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change that activates signaling via G-proteins (PubMed:10926528, PubMed:12044163, PubMed:11972040, PubMed:16908857, PubMed:16586416, PubMed:17060607, PubMed:17449675, PubMed:18818650, PubMed:21389983, PubMed:22198838, PubMed:23579341, PubMed:25205354, PubMed:27458239). Subsequent receptor phosphorylation mediates displacement of the bound G-protein alpha subunit by the arrestin SAG and terminates signaling (PubMed:1396673, PubMed:15111114). Ref: uniprot.org
Left: Pig retinal section stained for rhodopsin by Immunohistochemistry with mouse antibody to Rhodopsin (green). Rhodopsin is most abundant in the rod outer segments (ROS) of retina, clearly localized in rod membranes. The rod inner segments (RIS) and rod nuclei in the outer nuclear layer (ONL) are also seen in this image. Nuclear DNA was stained with DAPI (blue). Right: Western Blot of bovine retinal extract probed with mouse antibody to Rhodopsin. The antibody stains a band corresponding to retinal rhodopsin at about 35 kDa. Higher molecular weight bands represent aggregated forms of rhodopsin.
