概要: The second near-infrared window ranged between 900 and 1400 nm, namely NIR-II, has advantages for deep tissue imaging with extrinsic fluorophores due to lacking autofluorescence, low light absorption, and reduced scattering. Most of … the proposed probes were used for labeling with antibodies. As a new application, we plan to monitor electrical activity in a living tissue noninvasively using membrane potential dye with NIR-II fluorescence. So we need the excitable cell culture system to screen candidates of such dyes. C2C12 skeletal myoblasts were morphologically differentiated to myotubes under the optimal conditions, and the electrical stimulation-induced contraction of the myotubes was monitored optically. This myotube system would permit screening membrane potential dyes in NIR-II. 続きを見る
