A two‐photon probe (BCaM) shows 14‐fold enhancement in two‐photon emission fluorescence in response to Ca2+ and shows high sensitivity and selectivity for near‐membrane Ca2+ ions (see picture). Combined with the known Na+ two‐photon probe ANa1, BCaM allows simultaneous dual‐color imaging of Ca2+/Na+ activities within live cells and in tissues at more than 100 μm depth for long time periods without
一个双光子探针(BCaM)在响应Ca 2+的情况下显示了双光子发射荧光增强了14倍,并且对近膜Ca 2+离子具有很高的灵敏度和选择性(参见图片)。与已知的Na +双光子探针ANa1结合使用,BCaM可以长时间对活细胞和组织内深度超过100μm的组织中的Ca 2+ / Na +活性进行双色成像,而无需进行光漂白。
