產品物理化學光譜特性
分子量：1024.27
溶劑：水
與Fluo-4等單波長探針不同，對于Ca2+，Fura探針的大吸收（或熒光激發）從380 nm（Fura-2），415 nm（Fura-8和Fura-10）轉變，與Ca2+結合的無螯合劑可達到約340 nm（Fura-2），355 nm（Fura-8和Fura-10），大熒光發射的波長相對獨立于Ca2+濃度。通過使用在340nm和380nm（對于Fura-2），355nm和415nm（對于Fura-8和Fura-10）進行激發并分配熒光強度來獲得Ca2+依賴性熒光信號的大動態范圍在?510 nm（Fura-2），525 nm（Fura-8和Fura-10）處檢測到。根據該比率，可以使用從校準曲線得出的解離常數（Kd）估算細胞內Ca2+的水平。通過使用在兩個波長下激發產生的熒光強度之比，諸如染料分布不均勻和光致漂白等因素將被小化，因為它們應在相同程度上影響兩種測量。校準溶液初應不含重金屬離子，例如錳，這可能會影響其熒光和對鈣的親和力。百螢生物是AAT Bioquest的中國代理商，為您提供的Fura-10，鉀鹽。
