Adenine 9-β-D-arabinofuranoside by Molecular Depot is a adenine 9-β-D-arabinofuranoside, a synthetic purine nucleoside also known as vidarabine or ara-A. Arabinose differs from ribose in the orientation of a single hydroxyl, and that inversion is enough for the nucleoside to be incorporated into a growing nucleic acid chain and then block its extension. It is used as an antiviral nucleoside analogue in virology research, as an adenylyl cyclase inhibitor in signalling studies and as a reference standard. Each unit contains 50 mg. MBP supplies Molecular Depot carbohydrate reagents to research labs in the United States, Canada and worldwide.
