Immunofluorescent analysis of Rhodopsin (green) showing staining in human retinal tissue (right) compared to a negative control without primary antibody (left). Formalin-fixed tissue was permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Tissue was probed with a Rhodopsin monoclonal antibody (Product # MA1-722) in 3% BSA-PBS at a dilution of 1:50 and incubated overnight at 4°C in a humidified chamber. Tissue was washed with PBST and incubated with a DyLight-488 conjugated secondary antibody in PBS at room temperature in the dark. Nuclei were stained with DAPI (blue) and images were taken at a magnification of 20x.

MA1-722 detects rhodopsin from human, mouse and bovine retinal samples. Clone 1D4 has also been used successfully in Zebrafish. It does not recognize rhodopsin in zebrafish rods, but instead labels long double cone outer segments that express red opsin (Yin, J. et al, 2012).
MA1-722 has been successfully used in Western blot, IHC (P), immunocytochemistry and immunoprecipitation procedures. By Western blot, this antibody detects an ~40 kDa protein representing rhodopsin from Sf9 cells expressing the bovine gene. Immunocytochemical staining of rhodopsin in human retinal samples results in staining of both rod and cone outer segments.
The MA1-722 immunogen is bovine rhodopsin. The epitope for this antibody has been localized to the C-terminal nine amino acids of bovine rhodopsin known as the 1D4 epitope.
Vision involves the conversion of light into electrochemical signals that are processed by the retina and subsequently sent to and interpreted by the brain. The process of converting light to an electrochemical signal begins when the membrane-bound protein, rhodopsin, absorbs light within the retina. Photoexcitation of rhodopsin causes the cytoplasmic surface of the protein to become catalytically active. In the active state, rhodopsin activates transducin, a GTP binding protein. Once activated, transducin promotes the hydrolysis of cGMP by phosphodiesterase (PDE). The decrease of intracellular cGMP concentrations causes the ion channels within the outer segment of the rod or cone to close, thus causing membrane hyperpolarization and, eventually, signal transmission. Rhodopsin and quote;s activity is believed to be shut off by its phosphorylation followed by binding of the soluble protein arrestin.
