Anti-CD19 Recombinant Immunotoxin (4G7(scFv)-ETA) (CAT#: BioBet-IT013Z) Datasheet

Target
CD19
IT Type
Antibody-based IT
Description
The immunotoxin includes (a) an anti-CD19 antibody lacking an Fc fragment, (b) a modified exotoxin A protein with both domains II and III, but lacking domain I, and (c) a peptide linker connecting the C-terminal end of the antibody to the N-terminal end of the modified exotoxin A protein. The linker is basically resistant to extracellular cleavage. The modified exotoxin A protein can be further modified to include a C-terminal KDEL sequence, which facilitates the transport of the protein to the endoplasmic reticulum of cells that have taken up the immunotoxin.
Indication
Refractory B-cell malignancies; B-cell Leukemia/Lymphoma
Classification
Immuntoxin; biobetter
Construction
4G7(scFv)-ETA

Toxic MOA
The exfoliative toxins (ETs) also known as epidermolytic toxins, are serine proteases secreted by S. aureus that recognize and hydrolyze desmosome proteins. S. aureus ETs are serine proteases, which exhibit exquisite substrate specificity, and their mechanisms of action are extremely complex. However, the exact molecular mechanisms of ET‐causing epidermal blisters had long been unknown over the three decades.

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