Product Introduction:
Alcian also known as Alcian Blue, is a kind of copper titanium cyan conjugate dye, which was originally used for textile fiber dyeing. This kind of cationic dye combines with acid group, that is, alcian blue forms insoluble complex with anionic group such as carboxyl group and sulfate group. Alcian Blue is composed of the central copper containing phthalocyanine ring and four isothiourea groups linked by thioether bond. The isothiourea group is moderately alkaline, making Alcian Blue with cation.
Alcian Blue Cartilage Stain Kit, pH 2.5 can distinguish the genus of mucus by different pH value of staining solution. When pH value is 1, carboxyl group(COOH) is not dyed, and sulfuric acid group(OSO3H) is dyed. When pH value is 2.5, COOH is dyed well, while OSO3H is dyed bad, which makes mucin sulfate and mucin saliva stain. This reagent is only suitable for scientific research, not for clinical diagnosis or other purposes.
