pDVWS501 was a genomic-length cDNA clone of dengue 2 virus, through which infec-tious virus (MON501) could be rescued. MON501 was neurovirulent in mice, whose E
Two tumor necrosis factor-( mutants MT1 (32Trp157Phe) and MT2 (2Lys30Ser- 32Trp157Phe) were constructed by site-directed mutagenesis. These mutants were soluble
The location of rRNA processing was analyzed by using in situ hybridization with ITS1 probe and immunolabeling of anti-fibrillarin mAb in pea (Pisum sativum) ro

为寻求新的食用油资源,发展了一种快速可靠的气相色谱-质谱联用方法,用于植物籽油中脂肪酸成分的定性鉴定和含量测定.所建立的方法成功用于葡萄籽、南瓜籽和猕猴桃籽等七种植
以鄱阳湖为研究对象,利用地物波谱仪在湖区进行高光谱测量和同步的水体采样实验,通过研究鄱阳湖水体的光谱反射率特征和实测总悬浮物(TSS)浓度之间的关系,建立了TSS浓度的遥感定量模型。结果表明,由于悬浮物的反射作用出现双峰特征,红光与近红外部分波段是TSS的敏感区域,敏感性红光波段大于近红外波段;一阶微分处理的593nm处一阶导数数据和TSS浓度的一元二次方程为反演的最佳模型。研究成果可为今后卫星遥
