鈣離子熒光探針Cal-590 鉀鹽是美國AAT Bioquest生產的鈣離子熒光探針，鈣的測量對于許多生物學研究至關重要。熒光探針顯示結合鈣的光譜響應，使研究人員能夠通過熒光顯微鏡，流式細胞儀，熒光光譜和熒光酶標儀研究細胞內游離鈣濃度的變化。 Rhod-2常用于紅色熒光鈣指示劑中。然而，Rhod-2 AM在酯酶水解后僅在活細胞中發生中度熒光，并且具有非常小的細胞鈣響應。 Cal-590 已被開發用于改善Rhod-2細胞負載和鈣響應，同時保持Rhod-2的光譜波長，使其與TRITC /Cy3®過濾器組兼容。在CHO和HEK細胞中，Cal-590 AM具有比Rhod-2 AM更敏感的細胞鈣響應。 Cal-590的光譜與FITC，AlexaFluor®488和GFP的光譜完全分離，使其成為用GFP細胞系或FITC / AlexaFluor®488標記抗體復合細胞內檢測的理想鈣探針。百螢生物是AAT Bioquest的中國代理商，為您提供的鈣離子熒光探針Cal-590 鉀鹽
