Xenopus non-Genetically Altered Strains

Wild-type animals, albinos and inbred Strains

Large stocks of these animals mean that we can almost always fulfil users’ requirements immediately but if you wish to order more than 50 frogs then please let us know by email at EXRC@xenopusresource.org as soon as possible.

The main Xenopus laevis stocks have a mixed background, including wild-caught frogs (used for pregnancy testing at Queen Mary Hospital Portsmouth originally and more recently obtained from Blades) and those from Nasco. These have been bred in house for 14 years with no other frogs bought in.

The albino animals are bred from parents that originated in Cambridge and were obtained from Warwick.

The Xenopus tropicalis “wild-type” stocks that are normally supplied are of the Nigerian strain and are inbred for 7 generations so their DNA sequence is similar to the published one. We can also supply Ivory Coast, TGA blue strains and the more inbred Nigerians.

Transport to your laboratory can be arranged by approved courier and charged to you or you may arrange to collect. Before sending, each batch of Xenopus laevis is checked for Bd and a selection of frogs is tested for embryo production.
