Anti-ERBB2 immunotoxin 4D5 (scFv)-DT
CAT#: AGTO-G022D
This immunotoxin was achieved by conjugating/fusing the Anti-ERBB2 scFv to Diphtheria toxin. It was expressed in CHO and purified with affinity chromatography. The immunotoxin selectively binds to tumor cells and the toxin enters cells by receptor-mediated endocytosis. Before the N-terminal 193 amino acids corresponding to the catalytic domain of DT enzyme, -II binding and elongation factor into the eukaryotic cell, the cell can catalyze specific elongation factor EF2 amide His699 of diphtheria ADP2 ribosylation occurs, thereby preventing protein synthesis and causes cell death. It was designed for treatment of SK-OV-3 tumor xenografts.

- Toxin Description
- Diphtheria toxin (Diphtheriatoxin, DT) is a cell toxin produced by diphtheria, is a protein toxin most commonly used in the construction of recombinant immunotoxin. Before the N-terminal 193 amino acids corresponding to the catalytic domain of DT enzyme, -II binding and elongation factor into the eukaryotic cell, the cell can catalyze specific elongation factor EF2 amide His699 of diphtheria ADP2 ribosylation occurs, thereby preventing protein synthesis and causes cell death.
- Applications
- This product is suitable for use in cytotoxicity assay, functional assay and immunotherapy.

Q&As
-
How does this immunotoxin cause cell death in target cells?
A: This immunotoxin works by binding to ERBB2 on tumor cells and entering via receptor-mediated endocytosis. The Diphtheria toxin (DT) component then catalyzes the ADP-ribosylation of elongation factor EF2, preventing protein synthesis and leading to cell death.
-
What is the composition of this recombinant product?
A: This product is a fusion protein achieved by conjugating the Anti-ERBB2 scFv (clone 4D5) to Diphtheria toxin. It is expressed in CHO cells and purified via affinity chromatography for use in cytotoxicity and functional assays.
