Xenopus embryos for in vivo studies of human disease gene function: Xenopus embryos are large and easily manipulated, and moreover, thousands of embryos can be obtained in a single day. Indeed, Xenopus was the first vertebrate animal for which methods were developed to allow rapid analysis of gene function using misexpression (by mRNA injection ...
The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
It is the only species in the genus Xenopus to have a diploid genome. [3] [4] Its genome has been sequenced, [5] [6] making it a significant model organism for genetics that complements the related species Xenopus laevis (the African clawed frog), [7] a widely used vertebrate model for developmental biology. X.
Morphological data suggest that Xenopus is the sister-group of all other pipids, [3] [4] whereas molecular data consistently suggest that Pipa is the sister-group of other pipids.

Xenopus egg extract is a lysate that is prepared by crushing the eggs of the African clawed frog Xenopus laevis. It offers a powerful cell-free (or in vitro ) system for studying various cell biological processes, including cell cycle progression, nuclear transport , DNA replication and chromosome segregation .
Mycobacterium xenopi is a slow-growing scotochromogenic species of Mycobacterium.It was first reported by Schwabacher [1] in 1959, having been isolated in lesions found on a Xenopus laevis, but the possibility of human infection was not confirmed until 1965.
The Kivu clawed frog (Xenopus vestitus) is a species of frog in the family Pipidae found in the Democratic Republic of the Congo, Rwanda, and Uganda.Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude grassland, rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, arable ...
Square brackets are used with phonetic notation, whether broad or narrow [17] – that is, for actual pronunciation, possibly including details of the pronunciation that may not be used for distinguishing words in the language being transcribed, but which the author nonetheless wishes to document. Such phonetic notation is the primary function ...
