Abstract

The covalently linked antigenic complex, bovine serum albumin-alpha-linolenic acid, was used to immunize Balb/c mice against the hapten. Hybridization between splenocytes and the myeloma cell line, P 3 X63 Ag 8,651, resulted in stable clones synthesizing monoclonal antibodies (Mab) that were subsequently purified and characterized. Four Mab (A, B, C, D) were retained and their specificities studied by ELISA. Antibody D only recognized 18-carbon fatty acids having a cis,cis,-cis-1,4,7 unsaturated system in the omega-3 position: it was specific for alpha-linolenic acid. B recognized all fatty acids containing the structure cis,cis,cis-1,4,7-octatriene. A and C recognized polyunsaturated fatty acids with a degree of unsaturation superior to two double bonds.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
