Description
L-Selenomethionine (SeMet), a naturally occurring amino acid, is the predominant form of selenium found in Brazil nuts, grains, soy beans, and legumes. It promotes cell cycle progression and is known to elevate the expression of the antioxidant enzymes thioredoxin reductase, glutathione reductase, and glutathione peroxidase. At 5 μM, SeMet has been shown to selectively induce apoptosis in LNCaP prostate cancer cells without affecting non-cancerous cells.Related product price
