Nasco will stop selling Xenopus
The number of companies that supply live Xenopus to the research community is changing, but don’t worry, you have plenty of good options!
• Xenopus Express and Xenopus1 are two trusted commercial suppliers, and there are 4 international stock centers: the EXRC (UK), NXR (USA), NBRP (Japan) and CRB (France).
• Xenopus Express and Xenopus1 are excited to work with new customers and they have capacity to cover the additional animals when Nasco closes. Please reach out to each company to ask about their frogs and their availability.
• The EXRC and NXR have the ability to increase number of their wildtype frogs for sale if necessary. Contact Marko Horb (NXR) or Matt Guile (EXRC) to discuss.
