Your orders shape the future of the Xenopus model
Our focus will always be supporting a sustainable model system for all frog users. We have never had a mass die-off. Not even in one system. Our spontaneous mortality rate is 0.0003%. Leverage our 120 separate static-redundant systems to move your research forward.
Xenopus 1 is the long-term backbone of Xenopus research. We survive only if colonies stay healthy and research stays reproducible, on demand.
Independent suppliers
Privately run operations whose existence depends on ongoing trust. Xen1 incentives are aligned with model stability and worldwide access. We support the Model Welfare Organization.
Worldwide Stock Center
We worked with Nasco in 2021 to continue providing the most validated lineage of frogs, Nasco Xenopus 1 husbandry represents 80 years of husbandry.
(Note: First gen outbred stocks from African origin parents available June 2026-that's community support!).
Why it matters: Every order from Xenopus 1 is a vote for distributed, honest, real-world expertise and a resilient model system. You are helping keep supply lines alive so the model doesn't hinge on a single institution. Our separate, static systems gives the Model System incredible security and redundancy.
What we provide
Frogs, oocytes, and customer support
Live Xenopus laevis and tropicalis, J Strain frogs, embryos, testes, and oocytes.
Embryos & tadpoles
Staged embryos and tadpoles for for all research needs and specialized protocols. Shipped when needed.
Oocytes (Xenoocyte)
High-quality oocytes for expression studies and electrophysiology, via our Xenoocyte line.
Specialized feeds & guidance
Aquatic frog diets developed in-house (XENPRO). Tip: Introduce small amounts of food and increase slightly as frogs begin to respond. Continue for about 10 minutes. If food is left on the bottom, you are feeding too fast or too much. We describe feeding as an event, not a dosage.

Why Xenopus 1
Model stewardship, not just animal sales
Independent backbone of supply
Established in 1980. We supply most of the frogs used worldwide. We are leaders in disease-free frogs, supported by egg washing and regular PCR data collection.
Incentives aligned with sustainability
Our business only works if colonies thrive and labs can rely on us over decades. That drives the best husbandry and stable pricing.
Stewardship-focused welfare
We collaborate with labs and vets to define welfare benchmarks rooted in water quality, density, and feeding behavior. Real work creates the best frogs.
Supporting the ecosystem
Every order reinforces a decentralized, resilient Xenopus model that remains accessible to more labs.
Voices from the field
Trusted by Xenopus labs worldwide
“Xenopus 1 has been our primary supplier for years. Shipments are predictable, and when we’ve had issues, they’ve worked with us to solve problems.”
“What we value most is the practical husbandry experience. The guidance we’ve received on density and water quality has had as much impact as the animals themselves.”
“Xenopus 1 understands that model sustainability means more than selling frogs. Their support for welfare work is essential.”
Beyond supply: a Xenopus model stewardship network
Xenopus 1 is part of a broader effort to keep frogs healthy, the model system sustainable & community supported. Our role is not only to ship animals — it is to help.
- Xenopus Welfare Org – a hub for promoting model sustainability.
- Ongoing collaboration with researchers and veterinarians.
Model welfare grounded in husbandry
Xenopus 1 treats husbandry and welfare as the core of model sustainability. We measure health by performance, long-term colony stability, and robust PCR data.
