Annexin V-PE Apoptosis Detection Kit Plus
產品描述:膜聯蛋白V-PE細胞凋亡檢測試劑盒Plus(Annexin V-PE Apoptosis Detection Kit Plus, K203) 可應用於細胞凋亡早期觀察 (initiating apoptosis)。在開始凋亡後不久,大多數細胞類型將膜磷脂磷脂酰絲氨酸(phosphatidylserine , PS)從質膜(plasma membrane)內表面轉移至細胞表面(cell surface)。一旦進入細胞表面(cell surface),通過用膜聯蛋白V(Annexin V- fluorescent)的螢光綴合物染色可以很容易地檢測PS,膜聯蛋白V (Annexin V)是一種對PS具有強烈天然親和力的蛋白質。一步染色程序僅需10分鐘。此外,該測定可直接在活細胞上進行,無需固定。Annexin V-PE凋亡檢測試劑盒Plus包括膜聯蛋白V-PE (annexin V-PE),SYTOX綠色染料(SYTOX Green dye)和結合緩衝液(binding buffer)。 SYTOX綠色染料(SYTOX green dye)對活細胞和凋亡細胞不可滲透,但通過與細胞核酸(cellular nucleic acids)結合而染色壞死細胞(necrotic cells),具有強烈的綠色螢光。在提供的結合緩衝液中用膜聯蛋白V-PE和SYTOX Green染料染色細胞群後,凋亡細胞顯示紅色螢光,死細胞顯示綠色螢光和,活細胞顯示很少或沒有螢光。這些群體可通過螢光顯微鏡使用FITC和PE filters或流式細胞儀使用FL1 channel(Ex.488 nm / Em.530 nm)用於SYTOX Green染料和FL2通道用於Annexin V-PE(Ex.488 nm)輕鬆區分/ Em.578nm)。
