NisslFluor™ Silver Nissl stain will stain the soma and proximal reaches of dendrites, cytoplasm, and nuclei of neurons a fluorescent silver/white color under UV light excitation. Nissl substance is not normally found in the axon hillock or the axon itself. NisslFluor™ Silver will be of high contrast, resolution, and brightness and resistant to fading. Visible under blue light (450-495 nm) excitation. This fluorochrome demonstrates little fluorescence under green light excitation (500ﾖ570 nm) or UV excitation (330-380 nm).
