Catalog Number: (PRSI55-200)
Supplier: ProSci Inc.
Description: Vitamin A metabolism is important for vital processes such as vision, embryonic development, cell differentiation, and membrane and skin protection. The protein encoded by this gene is a key enzyme in beta-carotene metabolism to vitamin A. It catalyzes the oxidative cleavage of beta,beta-carotene into two retinal molecules.

Catalog Number: (BOSSBS-9575R-A350)
Supplier: Bioss
Description: The retinal pigment epithelium (RPE) is a monolayer simple epithelium in proximity to the outer surface of the retinal photoreceptor cells. Retinal pigment epithelium-specific protein (RPE65) is a 65 kDa protein belonging to the β-carotene dioxygenase family. This protein is important in 11-cis retinal production as well as in visual pigment regeneration. RPE65 is attached to the membrane by a lipid anchor when palmitoylated (membrane form) and soluble when unpalmitoylated. The soluble form of the protein binds vitamin A. Defects in RPE65 causes autosomal dominant retinitis pigmentosa and/or Leber congenital amaurosis type 2.

Supplier: Cayman Chemical
Description: Lutein (Xanthophyll) is a natural yellow carotenoid, which can be found in plants, egg yolks, and in the human retina. It is a lipid-soluble antioxidant that can circulate in the plasma and confer cardioprotective, anti-inflammatory, and anti-angiogenic effects. Dietary lutein, in combination with zeaxanthin, vitamins and ω-3 fatty acids, may be beneficial against age-related macular degeneration and cataract development.
