The nissl stain
WebNissl staining. Nissl staining was performed with a kit according to the manufacturer’s instructions (Beyotime, Cat# C0117, Shanghai, China). Briefly, sections (bregma 0.5 mm to −2.0 mm) were placed in cresyl violet solution at 37°C for 8 min, washed with distilled water twice for 30 s, dehydrated twice with 95 and 100% ethanol for 2 min ... The functions of Nissl bodies are thought to be the same as those of the rough endoplasmic reticulum in general, primarily the synthesis and segregation of proteins. Similar to the ergastoplasm of glandular cells, Nissl bodies are the main site of protein synthesis in the neuronal cytoplasm. The ultrastructure … See more In cellular neuroscience, Nissl bodies (also called Nissl granules, Nissl substance or tigroid substance) are discrete granular structures in neurons that consist of rough endoplasmic reticulum, a collection of parallel, membrane … See more "Nissl stains" refers to various basic dyes that selectively label negatively charged molecules such as DNA and RNA. Because ribosomes are rich in ribosomal RNA, they are strongly basophilic ("base-loving").
