本协议描述了一种双光子钙成像的方法在树突和活神经元的棘。该技术可用于海马、小脑和新皮层的急性切片,也可用于切片和神经元培养。它使用两个荧光检测通道提供钙浓度的定量估计,并尽量减少所需的钙指示剂浓度。提出了一种通过荧光光强度(∆F/F)的分数变化来估计钙浓度的方法,以及两种加载钙指示剂神经元的方法。
This protocol describes an approach to two-photon calcium imaging in dendrites and spines of living neurons. The technique can be applied to acute slices from hippocampus, cerebellum, and neocortex, as well as to slice and neuronal cultures. It uses two fluorescence detection channels to provide quantitative estimates of calcium concentration and to minimize the required concentrations of calcium indicator. A method for estimating calcium concentrations from fractional changes in fluorescent light intensity (∆ F/F) is presented, along with two methods for loading neurons with calcium indicator.
