查询词典 transcription

It activates many virus and mammalian cells'promotors through the binding with GC/GT box, deciding the efficiency and specificity of the transcription of promotor. Sp3 gene turning out both activating and repressing function, even to the same gene, it can also develop the different function in different period, and therefore has got the important meaning to numerous genes of human body.

Sp3（Specificity protein，Sp3）基因是一种核转录因子，属Sp家族成员之一，是继Sp1后发现的具有与之相同的DNA结合区的转录调节因子，近年来发现它对众多基因均具有调节作用，它通过与GC／GT box结合，激活许多病毒和哺乳动物细胞的启动子，决定启动子的转录效率和特异性。

The PTZ plasmid vector was changed to plasmid vector pSP72, which contains both T7 and Sp6 promotors for transcription of antisense (T7) and sense (Sp6) RNA probe in vitro. The results revealed the label rate of cRNA probe is high, the hybrids between RNA-RNA are stable, so the background of hybridization is satisfactory.

本实验将质粒载体PTZ转换为带有T7和Sp6两个启动基因的pSP72载体，故可在体外转录cRNA时同时得到意义（Sp6为启动基因）和反意义（T7为启动基因）探针，实验结果表明，cRNA探针标记率高，杂合物稳定，故所获杂交反应背景较为满意。
