Health Standards

Taconic Biosciences® has developed clear and harmonized health standards to meet specific research requirements. Our health standards are defined by exclusion lists, husbandry practices, and testing methods and frequency. The standards can be grouped into barrier standards (with exclusion lists) and gnotobiotic isolator standards (in which all organisms in a location are known). A core list of rodent pathogens is excluded from all Taconic health standards. These health standards range from the most stringent health standard, Taconic germ-free (GF), to Taconic murine pathogen-free (MPF) where a select list of opportunistic bacteria are tolerated.  

Need help choosing the right Taconic Biosciences health standard for your research?

Use the health standard selector to enter your exclusion list. The tool will tell you which health standards meet your requirements.
