Rederivation (speed rederivation)

Are you concerned about the health status of your research models? We understand the impact of health status on the outcome of your experimental procedures. Your colony must be maintained within generally accepted target microbiological status specified within the FELASA Recommendations (FELASA, 2014). Envigo’srederivation servicestandardizes the reporting of microbiological status and allows animals to be exchanged between laboratories and breeders with the confidence that known microbial adventitious agents will not be inadvertently introduced.
