Production of bispecific antibodies

Current Protocols in Immunology
D M Segal, B J Bast

Abstract

Bispecific antibodies (bsAbs) contain two different binding specificities within a single molecule and can specifically bind two different molecules together. BsAbs can be produced by chemically cross-linking purified antibodies or Fab fragments with reducible disulfide bonds or nonreducible thioether bonds, both of which are described in this unit. Protocols are also presented for producing BsAbs by fusing two antibody-producing hybridomas that can be selected for based on drug resistance, or by double labeling with fluorochromes and FACS. Support protocols describe screening and purification of bsAbs.

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.
