Based on comparative studies, antigen recognition and positive reaction with CD19 transfected cell lines, the specificity of this antibody is the same as that of CD19 monoclonal antibody. It can detect 96 kD single chain glycoproteins on the surface of human B lineage cells (including pre-B cells). B cells can be detected in peripheral blood and tissues. The antibody can react with most B-cell malignancies, including chronic lymphocytic leukemia and most lymphomas, but does not include multiple myeloma.

Cellular reactivity:
Normal: Stain all B lymphocytes in peripheral blood and spleen. It is negative for granulocytes, monocytes, platelets, red blood cells and T lymphocytes.

Diphtheria toxin

35.64 kD

Diphtheria toxin (DT) is one of the most extensively studied bacterial toxins with intracellular action. The first 390 amino acid residues of DT (DT390) contain the catalytic domain or A chain of DT that inhibits protein synthesis by ADP ribosylation of elongation factor 2 (EF-2) and the translocation domain that translocates the catalytic domain to the cytosol by interaction with cytosolic Hsp90 and thioredoxin reductase.

The antibody portion mediated selective binding to target cells, while the toxin portion mediated translocation into the cytosol and subsequent cell killing.
