Enzo Life Sciences的GFP-CERTIFIED® FLUOFORTE® Calcium assay kit提供了一種熒光分析方法，用于檢測廣泛生物靶標的細胞內鈣動員情況。相對于其他商業(yè)化的染料，GFP-CERTIFIED® FLUOFORTE®染料是最亮和最-靈-敏的熒光鈣指示劑。該試劑盒為貼壁和非貼壁細胞系提供了更少步驟，更低變異性，更簡易的鈣檢測。此外，它既不需要洗滌步驟，也不需要添加外源性淬滅染料，避免了對受體-配體相互作用動力學的干擾。

Enzo Life Sciences的GFP-CERTIFIED® FLUOFORTE® Calcium assay kit可用于細胞內鈣離子的高通量檢測，鈣離子是重要的第二信使，常用于初步篩選中監(jiān)測G蛋白偶聯受體激活。

產品特色

● 可監(jiān)測表達GFP細胞中的鈣離子動員情況

● 最明亮、最-靈-敏的熒光Ca2+指示劑

● 獲得的 EC50和IC50值與使用鈣離子熒光探針 Rhod-4 AM和Fluo-4 AM 相當

● 更大范圍的檢測窗口

● 使用方便，無需洗滌，無需淬滅染料

實驗示例

圖2. U-2 OS細胞分別與（A）GFP-CERTIFIED® FLUOFORTE®AM染料和（B）Rhod-2 AM染料孵育。洗滌細胞并用終濃度為100nM的ATP處理，并立即成像。GFP-CERTIFIED® FLUOFORTE® AM染料比Rhod-2 AM表現出更亮的熒光強度。
