Rho1D4 Agarose

Proteins tagged with the epitope sequence of the Rho1D4 antibody can be purified with this affinity matrix. Rho1D4 peptide in the Elution Buffer serves to competitively bind to the affinity resin and release the tagged protein, providing gentler elution conditions than, for example, changing pH. Genaxon bioscience offers conveniently aliquoted Rho1D4 peptide that has been tested with Rho1D4 Agarose. Based on BioWorks Workbeads, this product is the first commercially available immunoaffinity resin for the Rho1D4 purification system.

Properties: 
- demonstrably suitable for membrane protein research 
- binding capacity of 3-4mg protein per mL resin 
- purifies protein with high specificity 
- gentle protein elution based on competitive binding 
- can be regenerated for reuse.

Genaxxon resins are produced under strict quality guidelines and each batch undergoes quality checks to ensure that the loaded matrix has a high protein capacity. Combined with the specificity of the antibody-epitope interaction, a purification protocol optimized for the target protein can generate elution fractions with exceptionally high yields. This set offers both the Rho1D4 agarose plus the Rho1D4 peptide for elution.

Human rhodopsin is a G-protein coupled receptor and an integral membrane protein of the light-absorbing molecules that mediate vision. It consists of a protein, opsin, which is covalently bound to 11-cis-retinal. Rhodopsin expression has been reported in rod-shaped photoreceptor cells of the retina. Retinitis pigmentosa is a hereditary disease of photoreceptor degeneration. Phosphorylation of rhodopsin at multiple phosphorylation sites is required for its rapid and reproducible deactivation.
