Anti-GPA33 immunotoxin (scFv)-α-sar

CAT#: AGTO-G034F

This immunotoxin was achieved by conjugating/fusing the Anti-GPA33 scFv to α-sarcin. It was expressed in CHO and purified with affinity chromatography. The immunotoxin selectively binds to GPA33 tumor antigen expressing cells. Once bind, alpha-Sarcin enters into the cells by receptor-mediated endocytosis and interacts with a single bond in the targeted ribosome and breaks it, causing the ribosome to be inactivated. It was designed for treatment of colon cancer.

Specifications

  • Host Species
  • Mouse
  • Species Reactivity
  • Human
  • Molecule Class
  • scFv-α-sar
  • Toxin Description
  • Alpha-Sarcin is a ribosome-inactivating protein produced in the mold Aspergillus giganteus. Specifically, alpha-sarcin cleaves the a portion of ribosomal RNA that forms the small ribosomal substrate. The high specificity of alpha-sarcin and its efficiency of cleavage are point of study and also account for this protein's very high toxicity level.
  • Applications
  • This product is suitable for use in cytotoxicity assay, functional assay and immunotherapy.
  • Related Disease
  • colon cancer
