實驗概要 Extension of overlapping gene segments by PCR is a simple, versatile technique for site-directed mutagenesis and gene splicing.Initial PCRs generate overlapping gene segments that are then used as template DNA for another PCR to create a full-length product.Internal primers generate overlapping, complementary 3‘ ends on the intermediate segments and introduce nucleotide sub......閱讀全文
基因工程小鼠的命名規則有沒有發現,當你在查詢或看paper時,往往會蹦出幾個賊長的,還夾雜著數字、上標、符號的名稱,比如:129-Trp53tm1Holl/J、FVB-Tg(PomcCre)5Brn...... 看上去很復雜的樣子。這些其實是基因工程小鼠的全名。如果把這一長串字符解構一下,常見的基因

對于一個剛出生的孩子而言,擁有好的遺傳基因和有一個好名字都挺重要,對于一家公司而言,也是如此。目前全球僅生物制藥公司的數量就成千上萬,公司名字也多種多樣,但是在公司的名字中有一個單詞似乎最受歡迎,它就是“gene”(基因)。 本文就是盤點那些名稱中全部或部分包含有“gene”的、最著名的生物制
經過近30年的發展革新,電轉染已成為基因的功能研究領域中不可或缺的技術手段。下文不僅是一篇新上市的轉染儀器的介紹,更是電轉染儀技術革新的介紹,因為: &nbs

來自中科院昆明動物所的研究人員發現在哺乳動物的一個重要轉錄抑制因子CDYL基因中,新外顯子反復在不同哺乳動物譜系中發生,而且這些新外顯子能給該基因帶來很大的功能改變,這說明基因中新外顯子的出現也是增加蛋白多樣性和新功能起源的一種重要方式。這一研究成果公布在國際著名遺傳學刊物《Trends in Ge
