Bauhinia purpurea Lectin (BPL/BPA) - HRP (Horseradish Peroxidase)
Price: Regular price $245.30
Product Description
Bauhinia purpurea agglutinin or lectin (BPA/BPL) is a tetrameric lectin with a molecular weight of 120 kDa. Binding is generally highest for glycoconjugates containing galactosyl (β-1,3) N-acetylgalactosamine structures, but oligosaccharides with a terminal α-linked N-acetylgalactosamine can also bind to BPL. BPA is lactose-specific and elutes with sugar lactose. It has specificity for blood groups A, B, and O (-SA). Treatment of erythrocytes with neuraminidase or trypsin increases the agglutination reaction, indicating that the receptor is masked by terminal carbohydrates. Makela's group 2 sugars, particularly N-acetyl-D-galactosamine, are potent inhibitors. Although the binding specificity of BPA is similar to that of peanut agglutinin, the tissue staining patterns of these two lectins are distinct.
Horseradish peroxidase (HRP) is a 40 kDa protein that catalyzes the oxidation of substrates by hydrogen peroxide, resulting in a colored or fluorescent product or the release of light as a byproduct of the reaction. It is commonly used for blotting, immunoassays, and immunohistochemistry methods. Bauhinia purpurea lectin (BPL/BPA) is conjugated to HRP at an appropriate ratio to provide optimal staining characteristics.
Recommended Usage: Recommended dilutions of 0.5 – 10 µg / ml in 1XPBS. Less than 1 µg / ml will agglutinate human or rabbit erythrocytes.
