The Alcian Blue (CI 74240) Analytical Grade by Dinâmica, available at LojaLab, is a cationic copper-phthalocyanine dye used in histology and histochemistry to reveal acidic tissue components. Binding occurs mainly with anionic groups of acidic mucins, glycosaminoglycans and proteoglycans. Selectivity changes with pH and ionic strength: pH 2.5 protocols generally cover carboxylated and sulfated groups, whereas more acidic conditions may favor strongly sulfated structures.
Characteristics
- Cationic dye identified by Colour Index 74240
- Copper-phthalocyanine-based structure
- Affinity for anionic groups of mucins and extracellular-matrix components
- Selectivity depends on pH, concentration, staining time and pretreatment
- Can be included in combined protocols such as Alcian Blue-PAS
Applications
- Demonstration of acidic mucins in histological sections
- Visualization of glycosaminoglycans and proteoglycans in cartilage and extracellular matrix
- PH-controlled histochemical protocols for differentiation of acidic groups
- Combined Alcian Blue-PAS staining to compare acidic and neutral mucins
- Research in pathology, histology, tissue biology and staining-method quality control.
