The eggs of Xenopus laevis intact, lysed, and/or fractionated are useful for a wide variety of experiments. This protocol shows how to induce egg laying, collect and dejelly the eggs, and sort the eggs to remove any damaged eggs.

TRPV2 is a non-specific cation channel expressed in sensory neurons, and activated by noxious heat. Particularly, TRPV2 has six transmembrane domains and three ankyrin repeats. TRPV2 has been cloned from various species such as human, rat, and mouse. Oocytes of Xenopus laevis an African clawed frog have been widely used for decades in characterization of various receptors and ion channels. The ...

BACKGROUND Natural products are well recognized as sources of drugs in several human ailments. In the present work, we carried out a preliminary screening of six natural compounds, xanthone V(1) (1); 2-acetylfuro-1,4-naphthoquinone (2); physcion (3); bisvismiaquinone (4); vismiaquinone (5); 1,8-dihydroxy-3-geranyloxy-6-methylanthraquinone (6) against MiaPaCa-2 pancreatic and CCRF-CEM leukemia c...

The viability of free-living glochidia of the freshwater pearl mussel (Margaritifera laevis) was studied in the laboratory at water temperatures of 10 degrees C, 15 degrees C and 20 degrees C. To obtain glochidia, gravid female mussels were collected from the Chitose River, inhabited by adult and juvenile mussels, and from the Abira River, where only adult mussels were found. Daily survival rat...

We point out new ways to search for charmless baryonic B decays: baryon pair production in association with η ′ is very likely as large as or even a bit larger than two body Kπ/ππ modes. We extend our argument, in weaker form, to B → γ + X s and ℓν + X. Although calculations are not reliable, estimates give branching ratios of order 10 −5 –10 −6 , where confidence is gained from recent experime...

We derive bounds on Higgs and gauge–boson anomalous interactions using the CDF data for the process pp̄ → γγγ + X. We use a linearly realized SUL(2) × UY (1) invariant effective Lagrangian to describe the bosonic sector of the Standard Model, keeping the fermionic couplings unchanged. All dimension–six operators that lead to anomalous Higgs interactions involving γ and Z are considered. We also ...

Xenopus laevis oocytes have been used to determine the intracellular localization of components of Ro ribonucleoprotein particles (Ro RNPs) and to study the assembly of these RNA-protein complexes. Microinjection of the protein components of human Ro RNPs, i.e., La, Ro60, and Ro52, in X. laevis oocytes showed that all three proteins are able to enter the nucleus, albeit with different efficienc...

The ability of Phanerochaete laevis HHB-1625 to transform polycyclic aromatic hydrocarbons (PAHs) in liquid culture was studied in relation to its complement of extracellular ligninolytic enzymes. In nitrogen-limited liquid medium, P. laevis produced high levels of manganese peroxidase (MnP). MnP activity was strongly regulated by the amount of Mn2+ in the culture medium, as has been previously...

Aipysurus laevis venom was chromatographed on CM-cellulose and Bio-Rex 70 columns. Three neurotoxic components, toxins Aipysurus laevis a, b and c, were isolated. The toxins a, b and c corresponded to 22, 33 and 21% respectively of the proteins in the original venom, and accounted for almost all the lethal activity of the venom. The three toxins a, b and c were monodisperse on disc electrophore...
