Preclinical Toxicological Testing Without Mammals. Deeptech specialized in alternative models alternative models Up to 90% less time. Up to 60% less costs
We are a deeptech specialized in alternative models that accelerate regulatory decision-making, reduce initial costs, and drive the safe development of new products.
Our Models and Services
Complete portfolio of toxicological tests with internationally validated alternative models.
Zebrafish
(Danio rerio)
Model vertebrate for developmental toxicology, neurobehavior, and drug safety studies. 70% genes homologous to humans.
Fruit Fly
(Drosophila melanogaster)
Widely validated invertebrate model, with a strong genetic basis and high conservation of biological pathways, ideal for functional toxicity, neurodegeneration, and genotoxicity studies.
Artemia salina
Microcrustacean
Crustacean widely used for initial screening of acute environmental and pharmacological toxicity with rapid response (24-48h).
Biochemical Analysis
(Redox Biology)
Investigation of toxic effects at cellular and molecular level, focusing on oxidative processes and antioxidant response, enabling a mechanistic understanding of the biological effects of different compounds.
