Nissl cresyl violet acetate

Manufactured by Merck Group
Sourced in United States

Nissl (cresyl violet acetate) is a histological stain used in the field of neuroscience. It is a cationic dye that specifically binds to the rough endoplasmic reticulum (Nissl substance) in the perikarya of neurons. This staining technique allows for the visualization and identification of neuronal cell bodies and their morphological characteristics.

Mapping Brain and Spinal Cord Biodistribution

Spinal cords and brain tissues from mice used for biodistribution were further analyzed through digital autoradiography. After perfusion and gamma counting, brain tissue was frozen in optimum cutting temperature compound (Sakura Finetek, Inc, Torrance, CA), and 20-µm-thick sections were cut using a cryostat microtome HM500 (Microm, Walldorf, Germany) at −20°C. Whole spinal cords and slides with brain slices were laid in a cassette and exposed to a 18F-sensitive storage phosphor film imaging plate (Fujifilm; GE Healthcare) for 20 hours at −20°C. Plates were scanned using a typhoon phosphorimager (Amersham Biosciences, Piscataway, NJ) and analyzed using ImageJ (image processing software, version 2.0.0). Brain section anatomy was confirmed by staining the exact same sections with Nissl (cresyl violet acetate; Sigma Aldrich, St. Louis, MO), as previously described.25 (link)

Spinal cords and brain tissues from mice used for biodistribution were further analyzed via digital autoradiography. Following perfusion and gamma counting, brain tissue was frozen in Optimum Cutting Temperature (O.C.T.) compound (Sakura Finetek, Inc.) and 20 μm-thick sections were cut using a cryostat microtome HM500 (Microm, Germany) at −20°C. Whole spinal cords and slides with brain slices were laid in a cassette and exposed to a 18F-sensitive storage phosphor film imaging plate (Fujifilm, GE Healthcare) for 20 hours at −20°C. Plates were scanned using a typhoon phosphorimager (Amersham Biosciences, USA) and analyzed using ImageJ (image processing software, version 2.0.0). Brain section anatomy was confirmed by staining the exact same sections with Nissl (cresyl violet acetate, Sigma Aldrich), as previously described.25

For real-time RT-PCR analysis, the lungs were removed en bloc, inflated with diluted Tissue-Tek OCT (Sakura Finetek USA., Torrance, CA, USA) (50% vol/vol) in ribonuclease (RNase)-free phosphate-buffered saline with 10% sucrose, immediately frozen in liquid nitrogen, and stored at -80°C [26 (link)]. The lungs were sectioned (12 μm) with a cryostat (Leica CM3050 S, Leica Biosystems, Wetzlar, DEU) and stained with 0.5% Nissl (Cresyl violet acetate) (Sigma Chemical, St. Louis, MO, USA)/0.1 M sodium acetate buffer for laser capture microdissection (LCM) of the bronchiolar epithelial cells using a Zeiss PALM Microbeam Laser Microdissection System (Carl Zeiss Microscopy GmbH, Jena, DEU). A total of 20,000 to 40,000 bursts of the laser were used to collect a minimum of 5,000 cells from each animal.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
