UNC2170 (maleate)

Improved Vectors for Selection of Transgenic Caenorhabditis elegans

the identification of transgenic animals within a background of non-transformed animals, the unc-119 gene is often used as a visible marker as the unc-119 mutants are small and move poorly and the larger size and smoother movement of rescued animals make them clearly

芯片毛细管电泳激光诱导荧光快速分离检测麻黄碱类兴奋剂

内充满运行缓冲液;在试样液池中加入试样溶液,使激光束聚焦于芯片分离通道下游离十字交叉口38 mm处。按下列程序分别向4个储液池施加电压,进行进样和分离操作：进样30 s，试样液池、试样废液池、缓冲液池、缓冲液分别施加1000、0、830、1000 V；分离120 s，试样液池、试样废液池、缓冲液池分别施加2170、2170、2600和0 V电压。 点击查看全文 芯片毛细管电泳激光诱导荧光快速分离检测麻黄碱类兴奋剂 分析化学研究报告.2006,34(12
