  1. The powder was then applied to a silica gel column chromatography charged with 80 % acetone in water and eluted with the same solvent. after concentrating and drying, relatively pure fr - 008 was obtained. hplc assay a comparison between antibiotic fr - 008 and candicidin has been made by studying the hplc separation profiles of antibiotic fr - 008, candicidin and a mixture of both

    對鏈黴菌fr - 008和灰色鏈黴菌imru3570的rflp分析發現，它們的染色體具有很高同源性； pfge的比較研究發現，這兩個菌株的明顯區別是鏈黴菌fr - 008攜帶有兩個線性質粒，而在灰色鏈黴菌imru3570中則沒有這兩個線性質粒。
  2. Methods isolates were identified as acinetobacter calcoaceticus by using antibiotic susceptibility test, plasmid profiles, restriction enzyme fingerprinting assay and plasmid elimination method

    方法對我院不動桿菌的感染進行調查，採用藥敏試驗、質粒抽提和限制性核酸內切酶分析法、質粒消除試驗。
  3. From the information available for the preparation to be assayed ( the “ unknown ” ), assign to it an assumed potency per unit weight or volume, and on this assumption prepare on the day of the assay a stock solution and test dilution as specified for each antibiotic but with the same final diluent as used for the usp reference standard. the assay with 5levels of the standard requires only one level of the unknown at a concentration assumed equal to the median level of the standard

    根據有效的信息制備試驗溶液，指定一個假定的每單位重量的效價或者體積，然後在假設的基礎制備當天儲備液試驗和稀釋溶液作為每一種抗生素指定的效價，但是當使用相同usp參考標準品的最終稀釋液時，試驗應使用平行5的標準要求僅有一份未知的做為濃度等同於中部的標準。
  4. In this study, pichia pastoris system had been utilized for expression of fmdv 2c3abc gene which aimed for establishing a sensitive and specific molecular dignosis method. first, 2c and 3abc genes were amplified individually from p2 and 3abc postive clones and ligated together using pcr method, then this 2c3abc product was cloned into pgem - t easy vector and transformed e. coli dh5a competent cell. a postive recombinant plasmid which contained whole 2c3abc gene had been confirmed by pcr, enzyme digestion and sequencing. after that, the 2c3abc gene was sub - cloned into ppiczaa expression vector and transformed e. coli dh5 a competent cell and selected by zeocin ? antibiotic. the postive recombinant expression vector was linerized and electro - transformed pichia pastoris smd1168 competent cell. a recombinant pichia pastoris had been obtained by zeocin ? antibiotics selection and induced with 0. 5 % methanol for target protein expression. the expression product was analysised by sds - page and western blotting assay. the result sh owed that 2c3abc gene was expressed successfully in pichia pastoris and the product was a 95ku fusion protein which could be recognized by anti - fmdv serum. the amount of target protein was over 15 % of the total bacteria protein by gel thin layer scanning analysis. this research had supplied materials for establishing a fmd diagnosis method to differentiate infected animals from vaccinated animals

    首先，用p2和3abc陽性克隆通過連接pcr方法獲得目的基因並將其克隆到pgem - teasy載體上，並轉化e colidh5a感受態細胞中，經pcr 、酶切以及測序證明得到了完整的2c3abc基因，並與國內外參考序列進行比較分析。然後，將目的基因亞克隆于ppiczaa表達載體並轉化大腸桿菌dh5a ，以zeocin ~ （ tm ）抗性篩選陽性克隆，大量提取重組表達質粒並用pme酶線性化后電轉化入畢赤酵母smd1168感受態細胞，通過zeocin ~ （ tm ）抗生素梯度濃度篩選，獲得重組酵母用0 . 5甲醇誘導表達，通過sds - page電泳、 westernblotting分析，結果表明， 2c3abc基因在畢赤酵母中成功表達，其表達產物為一95ku的融合蛋白，並能被口蹄疫病毒陽性血清識別。
