1.Methods:The 293T cells was cotransfected with PDG and an AAV plasmid containing human apoAIcDNA to produce infectious rAAV, and it was purified by non ionic iodixanol gradients followed by heparin affinity chromatography.
方法 :以质粒 PDG和含有人 apo AIc DNA的AAV载体共转染 2 93T细胞 ,继以 Iodixanol密度梯度离心结合肝素亲和层析法分离、纯化 ,斑点杂交鉴定 r AAV病毒颗粒数 ;收藏指正
2.Like 80 mmol/dm~3 K~(+), K~(+)-free or Mg~(2+)-free seawater would produce evidence of toxicity. The mechanisms of ionic control of settlement and metamorphosis in the Styela canopus Savigny larvae were discussed.
3.A fluorescence quenching method was developed for determination of Hg2+ with rhodamine 6G as fluorescent reagent. in polyvinyl alcohol solution potassium iodide and Hg2+ produce multi ionic associated substance with rhodamine 6G to quenching the fluorescence intensity of the system.
