Phaseolus limensis (Lima bean) Lectin (LBA) - Pure
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 itâ€°Ûªs carbohydrate- and metal-ion-binding activities.
This product comes in a lyophilized form and is stored at -20Ã¥Â¡C. Metal ions calcium and manganese are required for binding.
