Arachis hypogaea Lectin (PNA) - FITC (Fluorescein)
Price: Regular price $150.08
Product Description
Arachis hypogaea agglutinin (PNA) is purified by affinity chromatography (SKU: 21510000) and is consisting of four subunits of approximately 27,000 each. This lectin has an isoelectric point between pH 5.5 and pH 6.5. It has a carbohydrate specificity for Galβ3GalNAc with an eluting sugar of galactose. Galactose and lactose are poor inhibitors while disaccharide Gal β(1->3) GalNAc and desialylated human erythrocyte N-substance (T-antigen which is present in many M and N blood groups) are potent inhibitors of PNA. PNA may be used for clinical determination of T-polyagglutinability of erythrocytes and probing cell membranes of normal and malignant cells. This Lectin can be of use in characterization of tumor-specific antigens on the surface of malignant cells. It can be employed in the fractionation of stem cells in mice for use in bone marrow transplantation across histocompatibility barriers.
Arachis hypogaea (Peanut) Lectin (PNA) is labeled with fluorescein isothiocyanate (FITC) and has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin.
Recommended Usage: Recommended dilutions 0.5 – 10 µg / ml in 20 mM Tris buffer containing 1mM CaCl2 and 0.5 mM MnCl2, 50 mM NaCl. Less than 1 µg/ml will agglutinate human erythrocytes neuraminidase treatment of the cells.
