S3E8 - Venoms and coagulation: when evolution reveals useful for drug and assay development.
Welcome to Ask Stago, The Podcast dedicated to provide expert answers to your expert questions in coagulation.
In today’s episode, our guest Dr Bryan G Fry, aka Venom Doc, will make us enter his world and understand how venom interact with coagulation and how they can prove useful for assay or drug design & development
