Bacterial Adhesion

Bacterial adhesion

   

CONTEXT

Similarly to all other non-validated tests, users are completely free to develop their own protocol and thus to get test perfectly adapted to their specific needs. This includes thus a multitude of possibility regarding protocol steps (pre-incubation, application, rinsing…) and used endpoints (biochemistry, molecular biology, OMICS, cell imaging...). Moreover the main advantage is the possibility to use well-known references as positive and negative control that may be different from regulatory toxicological ones.

 

DESCRIPTION

Since several years research projects show clearly the important impact of bacteria on both human epithelia and epidermis. Our reconstructed tissues provide a tool of choice to study epithelial and skin microbiome since in vitro tissues can be colonized by commensal or pathogen bacteria (please note the possibility to order specific culture medium without antibiotics). 

Example of applications:

  • Research on bacterial adhesion mechanism
  • Candidosis understanding
  • Candidosis treatment discovery
