Anti-TFRC immunotoxin HB21 (scFv)-RTA (CAT#: AGTO-G067R)
This immunotoxin was achieved by conjugating/fusing the Anti-TFRC scFv to ricin toxin. It was expressed in CHO and purified with affinity chromatography. The immunotoxin selectively binds to tumor cells. Then the ricin A chain is incorporated into the cell by receptor-mediated endocytosis, blocking ribosomal protein synthesis and ultimately leading to cell death. It was designed for treatment of malignant.
We specialize in custom recombinant antibody production, offering seamless execution from provided sequences to high-quality antibody deliverables, ensuring optimal yield and purity.

Specifications

- Mouse
- Species Reactivity
- Human
- Clone
- HB21
- Molecule Class
- scFv-RTA
- Toxin Description
- Ricin consist of two polypeptide chains, A and B, linked by means of disulfide bridge(s). Cytotoxicity is associated with the A chain and its 15 inhibition of protein synthesis in nucleated cells. The B chain is essentially a delivery vehicle for the A chain. The B chain recognizes polysaccharide units at the surface of cells and creates a high affinity interaction with such units. Once the B chain binds with polysaccharide units at 20" the celL surface, the A chain is incorporated into the cell, blocking ribosomal protein synthesis and ultimately leading tocell death. The use of ricin A chain is preferred in this invention.
