Cresyl violet stained partial brain section of a Macaque. It is used in biology and medicine as a histological stain. Cresyl violet is an effective and reliable stain used for light microscopy sections. Initially, tissue sections are "defatted" by passing through graded dilutions of ethanol. Then, rehydrated by passing back through decreasing ...
Gram-positive bacteria have a thick mesh-like cell wall made of peptidoglycan (50–90% of cell envelope), and as a result are stained purple by crystal violet, whereas gram-negative bacteria have a thinner layer (10% of cell envelope), so do not retain the purple stain and are counter-stained pink by safranin. There are four basic steps of the ...
Haematoxylin (hematoxylin in North America) is a nuclear stain. [10] Used with a mordant, haematoxylin stains nuclei blue-violet or brown. [10] It is most often used with eosin in the H&E stain (haematoxylin and eosin) staining, one of the most common procedures in histology. [10]
Bielschowsky silver stain showing the processes of basket cells in the cerebellum.. The Bielschowsky technique is a silver impregnatiom method used in histochemistry for the visualization of nerve fibers, [1] including multipolar interneurons in the cerebellum.
Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic properties and was formerly important as a topical antiseptic.
Photomicrograph of Nissl bodies (two are indicated by arrows) in the cytoplasm of motor neurons in the anterior horn of the spinal cord; cresyl violet stain (purple) along with a luxol fast blue stain for myelin. Scale bar = 30 microns (0.03mm). Drawing of a motor neuron from the ventral horn of the medulla spinals of a rabbit.
Cook for 10 minutes and flip. Cook until the drumsticks are deep golden brown, crispy, and an instant-read thermometer registers least 165°F in the thickest part of the leg, 8 to 12 minutes more ...
Micromass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. Alcian blue (/ ˈ æ l ʃ ə n /) is any member of a family of polyvalent basic dyes, of which the Alcian blue 8G (also called Ingrain blue 1, and C.I. 74240, formerly called Alcian blue 8GX from the name of a batch of an ICI product) has been historically the most common and the most reliable member.
