GEMS: Genetically Engineered Mouse and Rat Models

Several unique Taconic Biosciences programs bring GEMs to the research community faster and more efficiently than ever before.

Live Models

Offers ready access to fully licensed transgenic models available off-the-shelf in typical study quantities with full use rights. Our TTMs™ are widely used in ADME, metabolic and cardiovascular disease, neurodegeneration, short-term carcinogenicity bioassays, immunology, and oncology studies.
