Cicer arietinum lectin or agglutinin (CAL/CPA) is a homodimer composed of two subunits.This lectin is a glycoprotein that contains 4.5% neutral sugars and is basic in nature (pI: 9.0). Itâ€™s haemagglutination activity is inhibited by fetuin and desialylated fetuin with a carbohydrate specificity for fetuin and p-Nitrophenyl N-acetyl-Î±-D-galactoside. CAL possess complex-sugar specificity for N-glycans and N-acetyl-D-galactosamine, and elutes with acetyl-D-galactosamine. Although neither human or rabbit erythrocytes are agglutinated by this lectin, pronase-treated rabbit and human erythrocytes have been successfully agglutinated. None of the sugars, such as glucose, mannose or galactose, nor their derivatives, disaccharides, trisaccharides and tetrasaccharides have any effect on the agglutination of this lectin. bioWORLD produces crosslinked 6B SeparoporeÂ® appropriately coupled to Cicer arietinum Lectin (CAL/CPA) 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.
