Affinity purified Tulip sp. Lectin (TL) lectin is a tetrameric protein composed of four identical subunits which are not held together by disulfide bonds. TL is not blood group specific, but it does agglutinate type O erythrocytes more readily than either A or B cells. It has a carbohydrate specificity of N-acetylgalactosamine, galactose and fucose, and elutes with fetuin or thyroglobulin.Affinity purified Tulip sp. Lectin (TL) is immobilized to Separopore® 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.
