AlphaLISA Epigenetics Reagents
AlphaLISA Epigenetics Reagents 是由 Alpha 技術所延伸出來的便利產品,可適用於偵測 Peptide 或 Full-length 型式的 Histone 蛋白。具有高度專一性,可藉由偵測各種轉譯後修飾類型的 Histone 蛋白,精確定量組蛋白密碼 (histone code) 調控者(例如 Acetyltransferase、Methyltransferase、Deacetylase、Demethylase)的酵素活性。與 ELISA 產品相比,AlphaLISA 偵測試劑具有更加寬廣的偵測區間,可減少樣本稀釋比例的測試步驟;並且具有更精簡快速的實驗流程,讓研究者能夠更快取得定量結果!
偵測原理
AlphaLISA 偵測技術是由兩種核心物質所組成,一為 Donor bead,另一為 Acceptor bead。Donor bead 本身帶有光敏感物質「Phthalocyanine」,因此當以 680 nm 雷射光激發 Donor bead 時,此光敏感物質會催化周遭的氧分子形成活化態,並於作用範圍內激發鄰近的 Acceptor bead 產生化學冷光反應,此冷光能量會進一步轉移至 Acceptor bead 本身所帶有的螢光物質,使其最終產生 615 nm 螢光訊號。與其他偵測平台相比(例如 FRET、TR-FRET),AlphaLISA 技術的能量轉移有效距離長達 200 nm,因此不論是胜肽、重組蛋白、或是細胞內原始含有的蛋白質,皆可作為實驗偵測對象。具有專一性佳、靈敏度高、偵測區間廣泛以及流程簡單等多項優質特點。
在進行實驗時,研究者僅需自行準備 (1). 待測酵素與輔因子 (cofactor)、(2). 鍵結有 Biotin 的 Histone peptide substrate 或 Histone 全長蛋白,即可開始實驗。若是使用試劑盒類型產品偵測細胞內的 Histone 蛋白,則不需額外準備前述兩項材料。歡迎與我們聯繫索取適用產品建議與技術支援。
