Production of bispecific antibodies.
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.
