Affinity purified Lotus tetragonolobus lectin (LTL) is isolated from lotus seeds and is composed of 240 amino acid residues. LTL is a glycoprotein consists of four subunits. This lectin has different isoelectric points of pH 7.3, 7.6, 7.9, 8.2 and a carbohydrate specificity toward Î±-fucose, it is most inhibited by L-fucose. LTL is a fucose-binding anti-H(O) lectin. Transitional cell carcinoma of the human urinary bladder tends to metastasize when it strongly expresses binding sites for LTL. Affinity purified Lotus tetragonolobus Lectin (LTL) 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.
