Why do we use Xenopus oocytes?

Apoptosis: Xenopus oocytes provide a tractable model for biochemical studies of apoptosis. Recently, oocytes were used recently to study the biochemical mechanisms of caspase-2 activation; importantly, this mechanism turns out to be conserved in mammals.

What is Xenopus laevis oocytes?

Xenopus oocytes are a versatile expression system particularly suited for membrane transporters and channels. Oocytes have little background activity and therefore offer a very high signal-to-noise ratio for transporter and channel characterization.

What type of egg does Xenopus have?

Frog eggs Two species of Xenopus are regularly used by biologists, Xenopus laevis and Xenopus tropicalis. Both species are fully aquatic, and are easy to maintain in captivity. Frog eggs are large (~1.2mm diameter), produced in large quantities, and easy to manipulate.

What does the skin of Xenopus laevis produce?

The skin secretions of Xenopus include thyrotropin releasing hormone, caerulein, and xenopsin. Antimicrobial compounds (magainins) are also found in skin secretions (Kreil, 1996).
