X-linked retinitis pigmentosa GTPase regulator recombinant protein epitope signature tag (PrEST)
Anti-RPGR antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
RPGR (retinitis pigmentosa GTPase regulator) gene encodes a protein with sequence homology to the guanine nucleotide exchange factor for Ran GTPase. It contains six RCC1-like domains at the N-terminus. It functions in the long-term maintenance of photoreceptor viability. It is found in the Golgi and is involved in an interaction with RPGRIP1 (RPGR-interacting protein 1) for mediating vesicular transport-associated processes. These two proteins co-localize in the outer segment of rod photoreceptors. Defects in this gene have been associated with -linked retinitis pigmentosa (XLRP).
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
