Storage and Stability Store at room temperature for up to 4 months from date of receipt. If Alcian-Blue solution forms a precipitate, remove particulates by passage through a 0.22 or 0.45-micron filter.
How do you make Alcian blue solution?
Alcian blue solution, pH 2.5: Dissolve 1 g of Alcian blue (8GX) in 100 ml of 3% acetic acid solution….
- Deparaffinize and hydrate to distilled water.
- Stain in Alcian blue solution, pH 1.0 for 30 min.
- Blot sections dry with filter paper without rinsing in water.
What is Alcian blue used for?
Alcian Blue is a stain that is used to visualize acidic epithelial and connective tissue mucins. Mucins are a type of carbohydrate and are found in the GI tract and respiratory tract. Acidic mucins have a negative charge.
What does Alcian blue stain chondrocytes?
Alcian Blue Staining Kit Alcian Blue stains sulfated proteoglycans deposits that are indicative of functional chondrocytes and it is a useful tool when used with Lifeline® mesenchymal stem cells and Lifeline® ChondroLife™ Complete Chondrogenesis Medium.
What Colour does Alcian blue stain?
The Alcian blue at a pH of 2.5 will stain all acid mucins deep blue but will not color the neutral mucins. The subsequent application of the PAS technique will stain the neutral mucins bright magenta.
How do you remove Alcian blue stains?
Method
- Bring sections to distilled water.
- Stain in the Alcian blue solution 15 mins.
- Wash well in running tap water 5 mins (For lower pH solutions ie pH 1.0/0.2, drain and blot dry, to prevent removal of stain in water).
- Rinse in distilled water.
- Counterstain with neutral red stain 1 min.
Does Alcian blue stain cartilage?
Alcian blue and Alizarin red stain cartilage and bone, respectively. As a cationic dye, Alcian blue binds strongly to sulfated GAGs and glycoproteins, while Alizarin red, an anionic dye, binds to cationic metals such as calcium [1].
Is Alcian blue acidic?
Thus the standard Alcian blue – pH 2.5 stains all acidic mucins (Figure 3). In contrast, mucins that contain predominately carboxylated carbohydrates will stain strongly with Alcian blue – pH 2.5 but not with Alcian blue at a pH of 1.0.
How does Alcian blue?
Alcian Blue is a basic dye containing copper, which gives it the blue color. The stain molecules carry a positive charge and are attracted to the negative mucins. Adjusting the PH of the Alcian Blue solution allows the demonstration of sub-types of acid mucins.
How does Alcian blue stain cartilage?
As a cationic dye, Alcian blue binds strongly to sulfated GAGs and glycoproteins, while Alizarin red, an anionic dye, binds to cationic metals such as calcium [1]. Because cartilage contains higher concentrations of GAGs than any other tissue, it binds more Alcian blue.
