1. In order to introduce antitetanus immunoglobulin fragments into eukaryotic cells, either antitetanus F(ab')2 or Fab' fragments have been linked to carrier molecules. Aciclovir, horseradish peroxidase, wheat germ agglutinin, and transferrin were tried as carriers. 2. F(ab')2-aciclovir and Fab'-horseradish peroxidase were not internalized by NG108-15 neurohybridoma cells. 3. [Fab']2-wheat germ agglutinin and F(ab')2-transferrin conjugates were internalized into various cells. 4. F(ab')2-transferrin conjugates were made with three different linkers: N-succinimidyl 3-(2-pyridyldithio) propionate, bis-maleimido hexane, and bis-maleimidoethoxy propane. All three conjugates were internalized but had a different fate inside the cells.

D007140 Immunoglobulin Fab Fragments Univalent antigen-binding fragments composed of one entire IMMUNOGLOBULIN LIGHT CHAIN and the amino terminal end of one of the IMMUNOGLOBULIN HEAVY CHAINS from the hinge region, linked to each other by disulfide bonds. Fab contains the IMMUNOGLOBULIN VARIABLE REGIONS, which are part of the antigen-binding site, and the first IMMUNOGLOBULIN CONSTANT REGIONS. This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.
