At first, 1. 67 u g per well mcab all was coated on three wells of a plate, and then 1. 5 x 1011 phage virion was diluted and added, after incubating with the target, wash away unbound phage by tbst ( 0. 1 % tween - 20 ), the bound phage was eluted with ph 2. 2 tris - gly buffer and amplified, the specially bound phage was enriched by taking through addition binding / amplification cycles. ln the following cycles, the stringency of panning can be increased by raising the concentration of tbst or decreasing that of mcab all, collecting and titering the washing phage of last time and output phage in each round, the selective ratio and the false positive rate of each round were worked out, the gradually increasing of selective ratio and decreasing of positive rate shows that the panning was effective. after 4 rounds of panning, 11 phage clones were selected after competitive - ellsa, the dna samples of 8 positive clones and 1 negative clone were sequenced and all the foreign peptides inserted was also deduced, a clear consensus binding sequence emerged
在本實驗中，利用隨機12肽庫對抗豬瘟病毒（ classicalswinefeverviruscsfv ）糖蛋白me2的單抗a11進行表位篩選，經過四輪篩選以後，隨機挑取11個克隆作競爭- elisa檢測，結果表明，所挑11個克隆中，有9個克隆能對me2蛋白和a11反應產生抑制作用，抑制率最高可達64 ； dna測序以後經過dnastar軟體分析，發現它們的核心序列為anwralsl ，該核心序列與豬瘟病毒e2蛋白的28 - 35位氨基酸ttwkeysh具有同源性；夾心- elisa檢測和western - blotting試驗均證明所挑陽性克隆能被a11所識別；人工合成含核心序列的多肽經間接elisa試驗證實，也能被a11識別。 -
Three chloroplast transformation vectors including pds16s - cat, ptn1269 - bar and psp72 - n5 - bar - n3 were constructed, using ! 6s rrna or chln gene sequence as a homologous segment and cat or bar as a selective marker gene, respectively. foreign genes were introduced to the cells of d. salina by microprojectile bombardment method and a pilot chloroplast tran
3 .杜氏鹽藻葉綠體165出na基因的克隆和轉化載體的構建根據杜氏鹽藻的近緣藻類的葉綠體基因組序列資料，克隆了杜氏鹽藻葉綠體16srrna基因部分序列1100bp ，並利用克隆的16srrna鄭州大學2003年博士學位論文 -
To identify the transfected cells, we also constructed the gfp expressing plasmids which also attached the kozac sequence and nuclear localization signal to the gfp gene and the plasmids served as a selective marker for the transfected cells
為了區分被轉染的細胞，以附加kozac序列和核定位信號的gfp （ pcdna3 . 1 + kg ）作為被轉染的細胞的標記。 -
The main difficulty in development of microsatellite ( or simple sequence repeats, ssr ) is to screen the specific sequences flanking ssr, a method to screen microsatellite based on sampl was tested in the chinese shrimp. randomly selective bands ( s1k s13 > s14 > s22 > s24 ) were cloned and sequenced, 61bp, i57bp 147bp, 152bp, 298bp sequences were obtained respectively. no ssr were found inslk s s s22 apart from the sampl primers sequence, on the other hand, a ssr sequence of ( ga ) 39 were found in s24, which comprises aflp primers only
微衛星的發展主要受限於微衛星兩端旁側特異引物的篩選，本研究在中國對蝦中初步嘗試了基於sampl技術的微衛星標記開發，隨機選取了5個s枷pl條帶（ 511 、 513 、 514 、 522 、 524 ）進行了克隆測序，大小分別為161bp 、 157bp 、 147bp 、 152bp 、 298bp ，但在511 、 513 、 514 、 522四個片段中未找到引物序列外的微衛星序列重復; 524兩端引物均為傳統的aflp引物，在此測序片段中有一（ ga ） 39重復序列。 -
According to the present actual underground power system which neutral point is grounded through arc suppression coil in many supper big shaft, the development history and present situation of synthetic protection system used in hv flameproof switchgear are reviewed, and on the basis of analyzing the problems existed in high voltage flameproof switchgear, the selective leakage protective method based on the detecting harmonic direction of zero sequence current as well as the value of zero sequence voltage is proposed in this paper, and at the same time, harmonics extracting schematic and transforming circuit are also designed

The problem of signal processing for direct - sequence code - division - multiple - access ( ds - cdma ) signal over multipath frequency - selective mobile channels is considered. a new blind receiver is proposed. without the knowledge of the multiple - access interference users spreading code and the channel characteristics, the receiver achieves blind detection with prior knowledge of only the desired users spreading code and approximate timing. by using reduced rank adaptive decorrelating filter and adaptive multipath combiner which is based on decision - directed algorithm, the receiver gets the ability to combat both fading and the near - far effect at low cost. simulation results demonstrate that the proposed receiver offers high performance
本文研究多徑頻率選擇性衰落通道下直接序列擴頻碼分多址（ ds - cdma ）信號的處理問題，提出了一種新型的盲接收機.該接收機不需預知多址干擾用戶的擴頻碼，不需預知通道參數，只需已知期望用戶的擴頻碼和粗略的定時，就可以完成用戶的盲檢測.同時，該接收機通過降維自適應去相關濾波和基於判決指導的自適應多徑合併，來獲得低成本和良好的抗衰落、抗遠近效應性能.模擬結果驗證了本文提出的接收機的優良性能
