PNA, Rhodamine
- Supplier: Vector Laboratories
Product Description
- Peanut Agglutinin (PNA), Rhodamine, 5 mg. PNA binds preferentially to the T-antigen, a galactosyl (beta-1,3) N-acetylgalactosamine structure present in many glycoconjugates, such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). Even sialic acid which is not bound directly to the receptor sugars may inhibit binding. The presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence. This product has an appropriate number of fluorochromes to provide the optimum staining characteristics and is supplied essentially free of unconjugated fluorochromes. The excitation maximum is at 550 nm, and the emission maximum is at 575 nm.
