生物活性

製品説明 Vitamin E (D-alpha-Tocopherol) is a fat-soluble vitamin with potent antioxidant properties. It is a potent peroxyl radical scavenger and inhibits noncompetitively cyclooxygenase activity in many tissues, also inhibits angiogenesis and tumor dormancy through suppressing vascular endothelial growth factor (VEGF) gene transcription.
in vitro

this compound is capable of inducing necrosis in TC-1 cells and has antioxidant effects against nitric oxide[1].
in vivo

Vitamin E induces TC-1 cell necrosis in vivo and reduces tumor volume in TC-1 tumor-bearing mice. This compound reduces myeloid derived suppressor cells(MDSCs) in tumors of TC-1 tumor-bearing mice and enhances T cell accumulation[1].
密度 0.95 g/mL at 25 °C

プロトコル(参考用のみ)

細胞アッセイ 細胞株 TC-1 cells
濃度 0, 25, 50 μM
反応時間 18 h
実験の流れ

For in vitro cytotoxicity experiments, 1×105 TC-1 cells per well are added to 24-well plates. Eighteen hours later, tumor cells are treated with Vitamin E (0, 25, 50 μM). After 18 hours, apoptotic (Annexin V+ and 7AAD−) and necrotic (Annexin V+ and 7AAD+) cells are measured using PE Annexin V Apoptosis Detection Kit I.
