Arachis hypogaea Lectin (PNA) - Texas Red
Description
Peanut lectin (PNA) is purified by affinity chromatography and consists of four subunits, each of about 27,000 subunits. This lectin has an isoelectric point between pH 5.5 and pH 6.5. It is carbohydrate-specific for Galβ3GalNAc with galactose-eluting sugar. Galactose and lactose are poor inhibitors, while disaccharide galactose beta (1->3)GalNAc and defatalized human red blood cell substance N (t antigen, present in many M and N blood groups) are potent inhibitors of PNA. Texas red is a red fluorescent dye that, when combined with peanut lectin (PNA), can show the binding pattern of this lectin in cell imaging. There is little overlap between the emission spectra of Texas Red and FITC, making this combination ideal for double-labeling experiments. Rhodamine dyes, such as Texas red, have better light stability and are less sensitive to pH changes than other dyes such as fluorescein. This product is a stable liquid.
