  4. Many organisms produce enzymes, termed photolyases, that specifically bind to these damage products and split the via a uv - a / blue light - dependent mechanism ( photoreactivation ), thereby reversing the damage. these two photolyase are specific for either cpds ( cpd photolyase ) or 6 - 4 products ( 6 - 4 photolyase ). a gene that expresses a protein with 6 - 4 photolyase activity in vitro, was recently cloned from high organisms ( arabidopsis thaliam, drosophila melanogaster, danio rerio, xenopus laevis and homo sapiens )

    目前已從高等生物擬南芥、鮐類、果蠅、人類和非洲爪蟾蜍屬中克隆到有（ 6 - 4 ）光裂合酶活性的基因，本研究從鹽生杜氏藻dunaliellasalina中克隆到（ 6 - 4 ）光裂合酶的基因，並將該基因在大腸桿菌中得以表達，這是首次在藻類中克隆到（ 6 - 4 ）光裂合酶基因，對光裂合酶的研究具有重要意義。
  5. Sequence alignment shows that the fragment of pcr product showed some identities to the masp gene of xenopus laevis, branchiostoma belcheri, the trypsin gene in litopenaeus vannamei and the serine protease gene in aurelia aurita

  8. Intracelluar calcium spiral and target wave in xenopus laevis oocyte

    非洲爪蟾卵母細胞內的螺旋鈣波和靶波
  9. A critical and central component is likely to be mpf ( m - phase promoting factor, another name is maturation - promoting factor, it was first discovered by masui and marikert in 1971, and then purified from xenopus laevis eggs in 1988

    P34 ~ （ cdc2 ）有三個重要調節位點thr14 、 tyr15和thr161分別被其他各種因素調節，當thr161處于磷酸化，而thrl4 、 tyrls處于脫磷酸化時， p34拋才能被激活。
  10. Mpf is a complex that consists of the protein kinase p34cdc2 and the regulatory protein cycli b ; the protein kinase activity of p34cdc2 is strictly dependent on its association with cyclinb. in xenopus laevis eggs the absent of cyclin b, mpf will not be activited

    Ca卜活化p34 」擬的機制第一步是結合cycinb ，並且處于磷酸化狀態，即thr14 、 tyrls和tlirl61都處于磷酸化狀態；第二步是cdc25磷酸酶通過是thr14 、 tyr15脫磷酸化而激活p34 」擬。
  11. The temporal and spatial expression of gfap and vimentin of olfactory system of xenopus laevis during metamorphosis

    變形期非洲爪蛙嗅覺系統膠質原纖維酸性蛋白和波形蛋白的時空表達
  12. The cadherin repeated domains of bt - r3 protein share high homology with the cadherin domains from african clawed frog ( xenopus laevis ) and e - cadherin ( epithelial ) from mouse ( mus musculus ). so, the 3rd structure of the cadherin repeated domains of bt - r3 protein should be similar to these domains

    Bt - r3受體蛋白的鈣粘蛋白結構域分別與非洲爪蟾（ xenopuslaevis ）的鈣粘蛋白胞外結構域和小鼠（ musmusculus ）的上皮鈣粘蛋白胞外結構域有很高的同源性。
  13. At first, the vrl - cdna plasmids were transformed into tg1 r. coli to enlarge vrl - cdna ; then the plasmids were extracted and cut off with enzymes ; subsequently, vrl - cdnas were transcribed into vrl - inrna by t7 or sp6 polymerase in vitro, following vrl - mrnas were injected into xenopus laevis oocyte to express into vr1 receptor protein ; at the end the vrl + - oocytes were tested by double electode voltage clamp

    這項實驗中，我們首先將大白鼠vr1 - cdna質粒轉入大腸桿菌中進行擴增，然後提取質粒並酶切，然後在體外轉錄成vr1 - mrna ，接著將vr1 - mrna注射到非洲爪蟾卵母細胞中表達為蛋白質受體，建立了實驗模型細胞，最後用雙微電極電壓鉗檢測此模型細胞。
