fMLPinducedchemokinegeneexpressioninHMC1cells
Neutrophils respond to bacterial infection by releasing reactive oxygen species that kill bacteria and by expressing chemokines that attract other immune cells to the site of infection. The multisubunit enzyme NADPH oxidase expressed by neutrophils produces reactive oxygen species rapidly released in what is known as the respiratory burst. Activity of the NADPH oxidase is induced by fMLP receptor ligands, formylated ......阅读全文

克隆基因的表达（expression－of－cloned－gene）1
基因表达(gene expression)是指储存遗传信息的基因经过一系列步骤表现出其生物功能的整个过程。典型的基因表达是基因经过转录、翻译，产生有生物活性的蛋白质的过程。基因的表达主要涉及到两个过程：转录和翻译。 第一节影响外源基因表达的因素 利用基因工程技术高水平表达
克隆基因的表达（expression－of－cloned－gene）2
在双链 DNA 分子中，只有一条链转录成 mRNA，这条链称为有意义链(sense strand)，该基因的另一条链则称反意义链(antisense strand)。在含有许多基因的 DNA 双链中，每个基因的有意义链并不是在同一条 DNA 链上。也就是说，一条链上既具有某些基因的有意义链，
