Dark Green Powder Wright'S Stain CAS 68988-92-1 Biological Stains
Dark Green Powder Wright'S Stain CAS 68988-92-1 Biological Stains Overview Wright's stain is ready for direct use, requiring no preparation. A trace amount of neutral glycerol is added to the stain to prevent methanol volatilization or oxidation, while also allowing for clearer staining of blood cells. It is commonly used for blood and cell smears, bone marrow smears, and bacterial staining. Cytoplasm appears red, nuclei and bacteria appear blue, and eosinophilic granules

Chemical Reagents Giemsa stain CAS 51811-82-6 Biological Stains Diagnostic Reagents Analytical Reagents - colorants Introduction: Giemsa stain can be used as a dye intermediate and analytical reagent. It is used to determine indole, skatole, urea blue, tryptophan and ergot alkaloids, and is also used to distinguish serum eruptions from scarlet fever. In terms of dyes, it can be used to synthesize pressure-sensitive and heat-sensitive dyes. Uses: 1. Used as a protozoan stain,
Εωσίνη Υ όξινο ερυθρό 87 CAS 17372-87-1 Βιολογικά χρώματα και χημικοί δείκτες
Chemical Reagents Eosin Y/Acid Red 87 CAS 17372-87-1 Biological Stains and Chemical Indicators Introduction: Water-soluble eosin Y is a chemically synthesized acidic dye that dissociates into negatively charged anions in water and combines with positively charged cations of the amino groups of proteins to stain the cytoplasm. The cytoplasm, red blood cells, muscles, connective tissue, eosinophilic granules, etc. are stained in varying degrees of red or pink, forming a sharp
