trans-ε-Viniferin is a stilbene polyphenol and dimer of trans-resveratrol that has been found in various red wines. It induces disaggregation of aggregated amyloid-β (1-42) (Aβ42) fibrils and decreases Aβ42- and IL-1β-induced release of TNF-α and IL-6 in primary mouse neuron and astrocyte cocultures. trans-ε-Viniferin reduces cytotoxicity induced by truncated huntingtin (Htt) in PC12 cells. It also reduces production of reactive oxygen species (ROS), mitochondrial dysfunction, and PGC-1α depletion and increases protein levels and deacetylase activity of sirtuin 3 (SIRT3) in cells expressing mutant Htt. trans-ε-Viniferin inhibits calcium-activated chloride channel currents in HT-29 cells. In vivo, trans-ε-viniferin reduces rotavirus-induced secretory diarrhea in mice without affecting the rotaviral infection. Dietary administration of trans-ε-viniferin reduces hepatic triglyceride accumulation and body weight increases in a mouse model of diet-induced obesity.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
