Image Unavailable-BOSSBS-9575R-FITC

Anti-RPE65 Rabbit Polyclonal Antibody (FITC (Fluorescein Isothiocyanate))

Artikkenummer: (BOSSBS-9575R-FITC)
Produsent: Bioss
Beskrivelse: 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.

Lutein ≥98%, crystalline solid

Produsent: Cayman Chemical
Beskrivelse: 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.
