Xenopus Orexin A 是一种神经肽，其结构中包含两对二硫键（Cys4 - Cys10；Cys5 - Cys12），这两对二硫键对于维持其空间结构的稳定性起到关键作用 。 通过二硫键的形成，使得多肽链能够折叠成特定的三维结构，这种稳定的结构有助于其与相应受体的特异性结合，从而发挥生物学功能。

The frog pregnancy assay was simple: inject a small amount of a woman’s urine into a female Xenopus laevis. If the woman was pregnant, the hormones present in the urine—particularly human chorionic ...

Actually, they are quite similar. The three clawed frog species, Xenopus borealis, laevis and tropicalis, are about as closely related as a horse and a donkey. But when it comes to their comfort ...

The African Clawed Frog (Xenopus laevis) has become a well-understood and versatile vertebrate model organism for studies in developmental biology and other disciplines due to the availability of ...

This is an African Clawed Frog, or Xenopus laevis, one of the most studied of all amphibians.. Its basic biology is surprisingly similar to humans. A female Xenopus can produce up to 30,000 eggs in ...
