Technical Note: A simple procedure for mimicking tissue samples from CITES controlled animal species for use in DNA proficiency tests

Proficiency tests are an important practice in forensic laboratories. However, the range of species available for wildlife forensic proficiency testing is currently limited, especially for laboratories in Africa and Asia where CITES-listed species are frequently tested. Here we present a proof of concept of a novel sample type for use in proficiency testing based on textured vegetable protein impregnated with the synthetic DNA of a target species. This sample can act as a substitute for animal tissue and can be shipped internationally without CITES and/or biosecurity permits. This simple procedure can help laboratories ensure compliance with international standards and guidelines.
