The NisslFluor™ Nissl Sample Pack includes samples of NisslFluor™ Red (TR-200-NRD), Orange (TR-210-NOR), Green (TR-220-NGN), and Silver (TR-230-NSL). These products stain the soma and proximal parts of the dendrites, cytoplasm, and nuclei of neurons.

The NisslFluor™ Nissl Sample Pack includes samples of NisslFluor™ Red (TR-200-NRD), Orange (TR-210-NOR), Green (TR-220-NGN), and Silver (TR-230-NSL). These products stain the soma and proximal parts of the dendrites, cytoplasm, and nuclei of neurons. Nissl substance is not usually present in the axon hillock or the axon itself. The NisslFluor™ fluorescent Nissl stains fluoresce in different colors and are excited by green (500-570 nm), blue (450-495 nm), or UV light (330-380 nm). These stains resist fading and provide high contrast, resolution, and brightness. Please refer to the individual Nissl stain inserts for complete instructions on each stain.
Nissl substance, also termed chromophilic substance, exists as granular organelles in neuron cytoplasm. Named after its 19th-century discoverer, neurologist Franz Nissl, it consists of rough endoplasmic reticulum, RNA, and proteins and aids in protein synthesis for cell functions like growth and repair. Predominantly located in the neuron's soma, it's also in proximal dendrites but absent in axons. Its appearance and distribution vary based on the neuron type and activity. For instance, protein-synthesizing neurons like pyramidal cells contain large, basophilic Nissl chunks due to their maintenance needs, whereas sensory ganglion cells have dispersed, powdered forms. Typically, they're uniformly spread in the soma and dendritic regions, but their outward concentration might indicate neuronal damage or diseases, such as through central chromatolysis. Notably, after an axon is severed, its Nissl substance vanishes from the cell body. As a key neuronal activity and damage marker, changes in Nissl substance's size and distribution often signal stimuli response and are evident in conditions like Alzheimer's, where its reduction is linked to cognitive decline.
Healthy neurons: Nuclei, Soma, and Dendrites
Human
Staining Nissl substances are present in neuronal soma and dendrites, not typically found in axons. Note: Like their bright-field counterparts, Nissl stains will stain all cells in the brain, not just the neurons. However, the staining of non-neuronal cells will be limited to their nuclei and a very thin rim of cytoplasm. By contrast, the cytoplasm and proximal dendrites of the larger neurons will be quite prominent and easily noticeable.

This multipack contains sample volumes of products TR-200-NRD, TR-210-NOR, TR-220-NGN, and TR-230-NSL. These products will stain the soma and proximal reaches of dendrites, cytoplasm, and nuclei of neurons a fluorescent red, orange, green, or sliver color depending upon the specific stain used and its illumination. Nissl substance is not generally found in the axon hillock or the axon itself. Please see our website and the individual NisslFluor™ Nissl stain product listing to download the associated protocol for complete use instructions. The number of slides stained will depend upon the species and size of the sections used and the staining container. Using a typical 50 mL Coplin jar, 160 slides (two mouse brain sections per slide) could easily be stained in one afternoon. The entire kit will stain at least 800 slides.
