Overview of Alba v5
Alba v5是一个结合了各种测量模式的激光扫描显微镜，在实验量化生物学和材料科学中对单分子探测灵敏度有较高要求的情况下应用。它可以从光谱中的紫色区域至近红外区域进行采集，带有两个独立的激光入射端口。Alba v5由VistaVision驱动。VistaVision是一款综合性软件包，用于仪器控制、图像获取及处理。
Alba v5的关键特征
活细胞中的FLIM FRET
组织成像
单分子研究和通过反聚束实现的单个发射体探测
用相位图通过时间解析解混实现的多重成像
多模态成像
多模态成像 (强度、寿命和SHG)
铃兰的根茎横截面。图像由带有多光子激光器 (在800 nm处发射) 的Alba获得。标准荧光强度图像 (图1) 荧光寿命图像 (图2) 和二次谐波生成 (SHG) 图像 (图3)。 所有的图像都是256 × 256像素、40 × 40 µm2。

组织成像
自发荧光组织图像：激发：375 nm，发射：425 nm，物镜：20X NA0.75
(由GSK的Aneesh Alex博士提供)
活细胞中的FLIM-FRET
FLIM-FRET绘制了活细胞中共同表达Cerulean和Venus的Cebp/α 蛋白质FRET效率，以此在细胞核 (仅供体控制：仅表达Cebp/α-Cerulean的细胞；FRET样本：共同表达Cebp/α-Cerulean和Cebp/α-Venus的细胞)定位其二聚化
FRET效率图和强度图像的重合(Nature Protocols Vol. 6: 1324-1340, 2011)
使用相位图通过时间分辨解混合获得的多重成像
通过时间分辨荧光进行的多重成像需要使用单个激发波长，并且数据是在单个探测通道上获取的。上图显示了双标记的多重成像，同一细胞内用Alexa Fluor 647 (AF647) 标记的线粒体和Atto 647 (Atto647) 标记的微管。原始图像获取时是在640 nm处激发的，并且探测是在同一发射通道中进行的。利用相位图中的分析程式，两个结构可以被分开。
通过偏振成像实现的HomoFRET探测
Venus在海拉细胞内被表达。激发波长为514 nm，并且发射是通过带通过滤器545/35 nm完成的。发射中的分束偏振器会将荧光光束分成垂直和平行方向的光束，每一个光束由一个采集通道进行探测。各向异性图像在各个像素上被算出。对于单体 (右上) 来说，各向异性的平均值约为0.2，这说明了普遍的方向为沿着平行轴。对于六聚体来说，这一数值会小于0.1，这是由六聚体结构上不同Venus荧光蛋白质之间的局部homo FRET造成的。
单分子研究：通过反聚束探测单发射体
通过罗丹明110水溶液获得的反聚束数据 (488 nm处激发)。通过用经典Hanbury-Brown-Twiss装置将信号分成两束并把每个光束发送到Alba上分别的探测器以完成测量：采集电子设备能提供光子到达探测器处的时间差直方图。直方图在重合点处出现了下凹，凹陷的深度取决于观察体积中独立发射器的数量，而形状则由激发态寿命决定。
