Affinity purified Lens culinaris lectin (LCA) is composed of four subunits that consists of an Î±-chain (MW: 5.7 kDa) and Î²-chain (MW: 17.5 kDa). It has a carbohydrate specificity toward Î±-D-mannose and Î±-D-glucose, eluting with the sugar MeÎ±Man+MeÎ±Glc. This lectin is useful in affinity chromatography columns for the separation of glycoconjugates. The two isomers LCA-A and LCA-B agglutinates human red blood cells, although not blood group specific. Activity of LCA is determined by haemagglutination with human blood and agglutinates a 2% suspension of human erythrocytes at a lectin concentration of 8µg/ml. LCA requires calcium and manganese ions for binding. See other LCA conjugates.Affinity purified Lens culinaris Lectin (LCA/LCH) is immobilized to SeparoporeÂ® 4B following CNBr coupling. The final product is stabilized in a buffer to retain maximum activity. The gel can be packed in 1 mL or 5mL.
