偏振分辨荧光寿命成像(FLIM)可以提供关于荧光团的旋转扩散的信息。我们已经开发了一个宽场时间分辨荧光各向异性成像(TR-FAIM)系统定量成像荧光团的荧光寿命和旋转相关时间。在激发与线性偏振光,我们同时图像的平行和垂直偏振分量的荧光发射采用偏振分辨成像仪在前面的时间选通增强CCD。我们证明了这种技术通过成像的旋转相关时间的荧光素在不同粘度的溶液中的多孔板和活细胞。介绍
Polarization-resolved fluorescence lifetime imaging (FLIM) can provide information about the rotational diffusion of a fluorophore. We have developed a wide-field time-resolved fluorescence anisotropy imaging (TR-FAIM) system to quantitatively image both the fluorescence lifetime and the rotational correlation time of a fluorophore. Upon excitation with linearly polarized light, we simultaneously image the parallel and perpendicular polarization components of the fluorescence emission employing a polarization-resolved imager in front of a time-gated intensified CCD. We demonstrate this technique by imaging the rotational correlation time of fluorescein in solutions of varying viscosity in a multiwell plate and in live cells. Introduction
