Purification of peanut agglutinin by affinity chromatography on asialoglycophorin from human erythrocytes. 1983

K Starościk, and K Waśniowska, and D Syper, and E Lisowska

A simple and efficient method of purification of peanut agglutinin is described. This method involves affinity chromatography on human asialoglycophorin linked to Affi-Gel. One milliliter of the packed adsorbent contained 1.7 mg of covalently linked asialoglycophorin and bound about 6 mg of the peanut agglutinin. From 250 g of row peanuts 510 mg of the electrophoretically homogeneous lectin with high agglutinating activity was obtained.

D002846 Chromatography, Affinity A chromatographic technique that utilizes the ability of biological molecules, often ANTIBODIES, to bind to certain ligands specifically and reversibly. It is used in protein biochemistry.

D001212 Asialoglycoproteins Endogenous glycoproteins from which SIALIC ACID has been removed by the action of sialidases. They bind tightly to the ASIALOGLYCOPROTEIN RECEPTOR which is located on hepatocyte plasma membranes. After internalization by adsorptive ENDOCYTOSIS they are delivered to LYSOSOMES for degradation. Therefore receptor-mediated clearance of asialoglycoproteins is an important aspect of the turnover of plasma glycoproteins. They are elevated in serum of patients with HEPATIC CIRRHOSIS or HEPATITIS. Asialoglycoprotein,Desialylated Glycoproteins,Glycoproteins, Desialylated
D019887 Peanut Agglutinin Lectin purified from peanuts (ARACHIS HYPOGAEA). It binds to poorly differentiated cells and terminally differentiated cells and is used in cell separation techniques. Peanut Lectin,Agglutinin, Peanut,Lectin, Peanut
D037102 Lectins Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
