Anti-SAG Antibody

Housed in a 100 µl vial, this rabbit polyclonal reagent from Antibodies.com is raised against the retinal S-antigen, also known as arrestin, a key regulator of the phototransduction cascade in rod photoreceptors. The unconjugated IgG antibody is validated for Western blot detection of mouse SAG protein, supporting studies on photoreceptor signaling, light-driven protein translocation, and retinal degeneration models. Researchers investigating retinitis pigmentosa or experimental autoimmune uveitis can use this reagent to probe arrestin expression in retinal lysates and tissue homogenates prepared from mouse samples. The polyclonal format offers broader epitope coverage for recognition of full-length SAG under denaturing SDS-PAGE conditions, and the rabbit host species pairs with standard HRP-conjugated or fluorescently labeled secondary antibodies for chemiluminescent or imaging-based detection.
