The connective tissue and acidic epithelial mucins can be seen with the dye Alcian Blue. The GI system and respiratory tract both contain mucins, a kind of carbohydrate. Acidic mucins have a negative charge.
The negatively charged low-density mucin in the goblet cells will adhere to the positively charged, giant molecule of the alcian blue dye, coloring it blue. By adjusting the pH of the staining solution, the alcian blue can discriminate between the different acid mucins.
The neutral mucins are unaffected by the Alcian blue at a pH of 2.5, but the acid mucins are stained a rich blue color. The neutral mucins will become brightly magenta dyed due to the PAS technique's subsequent application.
A copper-containing dye is employed as a lubricant gelling agent for staining microorganisms and in vivo coloring of histiocytes and fibroblasts. American National Medical Library, 2021.
Cell mortality can be assessed using methylene blue staining. In a sample stained with methylene blue, a healthy cell will render the stain colorless—the enzymes in the cell cause the methylene blue to be reduced and lose its.
Almost any specimen can be operated using the Gram stain procedure.
Negative gram stain findings indicate that there were no microorganisms in your sample. They show the presence of bacteria if they are positive.
A basic dye called Alcian Blue prefers mucin and other acidic tissue components. The copper in the dye's molecule gives it its color.
Alcian blue is a water-soluble, blue-colored basic copper phthalocyanine dye. It contains copper. It has a preference for mucin and other acidic tissue components.
Additionally, it worsens nuclear and cytoplasmic polyanionic content, which lessens the strength of the differential staining between intracellular and external domains.
