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 ......閱讀全文

克隆基因的表達（expression－of－cloned－gene）1
基因表達(gene expression)是指儲存遺傳信息的基因經過一系列步驟表現出其生物功能的整個過程。典型的基因表達是基因經過轉錄、翻譯，產生有生物活性的蛋白質的過程。基因的表達主要涉及到兩個過程：轉錄和翻譯。 ? 第一節影響外源基因表達的因素 利用基因工程技術高水平表達
克隆基因的表達（expression－of－cloned－gene）2
在雙鏈 DNA 分子中，只有一條鏈轉錄成 mRNA，這條鏈稱為有意義鏈(sense strand)，該基因的另一條鏈則稱反意義鏈(antisense strand)。在含有許多基因的 DNA 雙鏈中，每個基因的有意義鏈并不是在同一條 DNA 鏈上。也就是說，一條鏈上既具有某些基因的有意義鏈，
