Nature, 1958
IN several genera of the order Anura supernumerary limbs occur naturally1. They are usually extra hind limbs2. Polymely does not appear to have been reported in the genus Xenopus. The female toad (Xenopus laevis) described here came with a consignment of toads imported from South Africa in 1956. The toad measured 8.0 cm.

Immunoglobulin classes in Xenopus laevis
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19741. 1. Electrophoretically pure 19 S and 7 S immunoglobulins, designated IgMand IgG, were prepared from Xenopus laevis serum. Both immunoglobulins possessed antibody activity. 2. 2. The sedimentation coefficient for IgM is 19·5 S, for IgG 6·1 S. Reduction and alkylation of IgM yielded subunits with a sedimentation coefficient of 4·1 S. 3. 3.

FGFR3 expression in Xenopus laevis
Gene Expression Patterns, 2010We studied the expression of FGF receptor 3 (FGFR3) mRNA throughout early development of Xenopus laevis by RT-PCR and in situ hybridization. RT-PCR shows that FGFR3 mRNA is localized within the gastrula; regionalized staining is detected by the neural plate stage and continues throughout embryonic development.

Raman spectroscopy of Xenopus laevis oocytes
Methods, 2010This work reports on the application of Raman spectroscopy for the analysis of Xenopus laevis oocytes (stage-I). A two-color home-made microscope has been used for this investigation. In particular, a 785nm Raman probe has been used to acquire the spontaneous Raman scattering from the oocyte cytoplasm, while a 532nm probe has been employed to detect ...

Alginate Coating of Xenopus laevis Embryos
Biotechnology Progress, 2000Xenopus laevis eggs were coated, immediately after squeeze-stripping and fertilization, with a thin layer ( approximately 50 microm) of film based on one of three different types of alginates which varied in their mannuronic/guluronic acid ratio. The alginate was cross-linked with either Ca or Ba ions at three different concentrations.

Journal of Molecular Biology, 1973
Abstract Ribosomal RNA synthesized by hybrid frogs from the cross between Xenopus laevis and Xenopus mulleri was analyzed by molecular hybridization with purified ribosomal DNA from each species. Although the 18 S and 28 S rRNA sequences are indistinguishable between these two species, the remaining 10% of the 40 S rRNA precursor molecule of each ...

The EMBO Journal, 1993
Fibroblast growth factor 3 (FGF3) was first identified as the product of a cellular oncogene activated by mouse mammary tumour virus but its normal role appears to be in the developing embryo. To gain further insights into its function, we have isolated sequences encoding the FGF3 homologue in Xenopus laevis, XFGF3.

Oligodendrocyte maturation in Xenopus laevis
Journal of Neuroscience Research, 1997Oligodendrocytes, the myelinating cells of the central nervous system, have a characteristic morphology, whose full extent is revealed immunohistochemically by the expression of specific markers. Proteolipid protein (PLP) is regarded as a terminal differentiation marker of oligodendrocytes.
