[Xenopus] Does anyone have really old Xenopus of known age?

[Levin, Michael]

Hi everyone, we have a collaborator doing some work on aging and he needs tissue from frogs of different ages to establish a molecular clock. Does anyone have really old Xenopus, such that you know how old it is?  Thanks in advance!
