Phaseolus limensis agglutinin (LBA) is isolated from lima bean seeds and purified by affinity chromatography. LBA is composed of 30, 000 Da subunits, of which two are joined by a disulfide bond. It has a carbohydrate specificity of terminal GalNAc(1, 3)Gal that elutes with N-acetylgalactosamine. LBA agglutinates blood group A erythrocytes but not blood groups B or O. Each subunit contains a cysteine residue which is required for both it’s carbohydrate- and metal-ion-binding activities. See other LBA conjugates.This product comes in a lyophilized form and is stored at -20?C. Metal ions calcium and manganese are required for binding.
