Implementation of a Triple-Function-Analysis Method for In vitro Detection of Fully Active Tetanus Toxin to Replace In vivo Animal Models

This project will improve the BINACLE (2013) tetatnus toxicity assay, to replace animal tests. The team will add a step to the assay to measure transport into the cell cytoplasm, a critical step in tetanus toxicity.

Industry Need

Replacing historical in vivo models with in vitro testing, however animal models remain the regulatory "gold standard".

Approach

This project will initiate the development of an in vitro assay to replace the in vivo testing of a licensed tetanus vaccine component, reducing or eliminating the need for animal testing.

Impacts

This project will initiate the development of an in vitro assay to replace the in vivo testing of a licensed tetanus vaccine component, reducing or eliminating the need for animal testing.

Outputs/Deliverables

  • Documentation for preparing tetanus toxin open structure detoxification
  • Material production information (SinBio) for translocation domain/heavy chain of tetanus toxin
