Transgenic and mutant lines

The EXRC holds over 200 genetically altered Xenopus lines. Many of these were created at the Centre. Others were deposited by researchers across the community.

When new lines arrive we breed them as soon as possible after they leave quarantine and the expression of the transgene in the offspring is checked. Images of the expression from these quality assurance matings are shown on the lines pages.  Data on the lines we hold can also be found on Xenbase.

We will arrange to collect frogs or frozen sperm from those depositing lines at our cost. If you require a line then transport to your laboratory can be arranged by approved courier and charged to you or you may arrange to collect.

As the number of lines grows, the less popular ones will mainly be held as frozen sperm and we will recover these and send embryos, or send the sperm as preferred.
