SPA Beads

由 SPA (Scintillation Proximity Assay) 鄰近閃爍分析技術所延伸出來的便利產品，微珠本身含有閃爍計數劑成分，具有全均質化的實驗操作步驟，可讓研究者省略麻煩的分離洗滌步驟，還可省下購買閃爍計數液或濾盤的費用。在進行 GTP Binding Assay 時，僅需先將受體或表現有受體的細胞膜鍵結固定在SPA Beads 表面，當帶有放射性標定的 GTP 與受體結合時，此時由於距離的靠近，使得放射線能量能夠與 SPA Beads 成分中所含有的閃爍計數劑產生能量轉移反應，使放射線轉換為光能，藉由光值的強弱變化即可了解待測藥物對於 GTP 與受體結合的影響性。

依據最終發光訊號波長的不同，可區分為適合以 CCD 影像系統偵測的 SPA Imaging Beads，以及適合以盤式輻射偵測儀偵測的 SPA Scintillation Beads。兩者皆有多種規格可供選擇，歡迎洽詢索取詳細技術資料。

選擇指南：

SPA Imaging Beads 與 SPA Scintillation Beads 分別具有兩種不同組成核心物質可選：

GTP Gamma S GPCR Assay

由 SPA (Scintillation Proximity Assay) 鄰近閃爍分析技術所延伸出來的便利產品，內含 WGA PVT SPA Beads 與 5X Assay Buffer，可供建立全均質化的 GTP 結合分析試驗。偵測原理是利用 SPA Beads 表面所帶有的 WGA 分子將受體表現細胞膜 (membrane prep.) 結合於微珠表面，當帶有放射性標定的 GTP 與受體結合時，此時由於距離的靠近，使得放射線能量能夠與 SPA Beads 成分中所含有的閃爍計數劑產生能量轉移反應，使放射線轉換為光能，藉由光值的強弱變化即可了解待測藥物對於 GTP 與受體結合的影響性。
