Bauhinia purpurea Lectin (BPL/BPA) - FITC (Fluorescein)
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.
Affinity purified Bauhinia purpurea lectin (BPL/BPA) (SKU: 21510028) is labeled with fluorescein isothiocyanate (FITC) and has an appropriate number of fluorochromes bound to provide optimum staining characteristics. FITC conjugates have been used in various immunohistochemical and flow cytometry applications. This product comes in a stabilized liquid form.
Recommended Usage: Recommended dilutions of 0.5 – 10 µg / ml in 1XPBS. Less than 1 µg / ml will agglutinate human or rabbit erythrocytes.
