Isolated from tomatoes, affinity-purified Lycopersicon esculentum lectin (LEL/LEA) has a carbohydrate specificity toward GlcNac. Composed of a single stable subunit, LEL is a useful marker of tracking vasculature in rodents and in neuroscience research. This lectin has an unusually high carbohydrate content of about 50 percent arabinose and galactose. LEL is non-specific agglutinates human erythrocytes A, B, O, or AB blood types. Protease-treated erythrocytes are slightly more sensitive to agglutination by this lectin.bioWORLD produces crosslinked 6B Separopore® appropriately coupled to Lycopersicon esculentum Lectin (LEL/LEA) to provide a fast flow cartridge which can trap affinity bound material and retain it during washing, followed by elution of affinity purified material. bioWORLDâ€™s SuperTrap cartridges of varies matrices are proven highly effective in protein chromatography.
