Culture of mg7 hybridoma cells and detection of antigen - binding affinity of mg7 mab by elisa 2. construction and identification of mg7 recombinant phage antibody library mrna was isolated from cultured mg7 hybridoma cells and converted into cdna ; the variable fragments of heavy and light chain were separately amplified and assembled into scfvs with a specially constructed dna linker by pcr. the scfvs dma was ligated into the phagmid vector pcantabse and the ligated sample was transfered into competent e. co / / tg1 to generate a bacterial form of mg7recombinant phage antibody library ; volume and recombinant ratio of the library were evaluated by means of bacterial colony counts and restriction analysis ( ecor i and hind iii )
Mg _ 7重組噬菌體抗體庫的構建及鑒定從培養的mg _ 7雜交瘤細胞中提取並分離mrna ，反轉錄成cdna ；利用pcr分別擴增mg _ 7單抗的重鏈及輕鏈可變區基因，並通過? dna連接子將二者連接起來形成mg _ 7單鏈抗體基因；將mg _ 7單鏈抗體基因插入pcantab5e ；將連接產物轉化感受態tg1大腸桿菌，制備細菌形式的mg _ 7重組噬菌體抗體庫；通過菌落計數和限制性酶切分析（ ecor和hind ）評估mg _ 7重組噬菌體抗體庫的容量和重組率。 -
High stability of ptr102 - derived marking plasmids indicated that novel vector systems based on ptr102 could be constructed for the study on molecular biology and ecology of m. huakuii. 1kb gfp cdna fragment amplified by pcr was cloned into e. coli expression plasmid pet - hc, which was under the control of rna polymerase gene promoter from phage t7 with its own translation initiation codon
將pcr擴增的1kbgfpcdna片段克隆到大腸桿菌表達載體pet - 11c上，使gfpcdna在帶有lac操縱基因的t7噬菌體rna聚合酶基因啟動子的控制下、以自身的atg作為翻譯起始密碼進行翻譯。 -

Thirteen putative epitopes showing characteristics of antigenic epitope were found from the analysis information. using pcr, the nucleotide acid fragments encoding these putative epitopes were amplified, then cloned into the expression vector miske. the positive recombinant phage displying the epitopes were found out by using pcr, sequencing and the determination of phage plaque titer
運用goldenkey分子生物學軟體對prrsvbj - 4結構蛋白的抗原表位及其二級結構進行了分析和比較，從中篩選13段顯示表位特徵的氨基酸殘基序列，用pcr技術擴增相應的核苷酸片段，將其插入到噬菌體表達載體m13ke ，結果預測的13個表位可在噬菌體表面得以展示。 -
The library was rescued with phage m13k07 in order to display scfv on the surface of the phage and to form the recombinant phage antibody library. one of positive scfv clones, named pcsal, was selected with phage - elisa after panning and screening by bull sperm three times. scfv fragment, amplified from pcsa1, was ligated to pmd18 - t vector for sequencing analysis
取陽性重組噬菌體抗體克隆株pcsa1 ， pcr擴增其scfv基因，篩選重組子進行序列測定，發現其序列符合小鼠抗體基因的一般特徵，並且與幾株抗磷酸膽堿的抗體重鏈和輕鏈可變區序列的同源性達80以上；推測pcsa1scfv針對的抗原是磷酸膽堿類物質。 -
Methods : a set of oligonucleotide primers were designed and used to amplify the vh and vl gene from anti - hbsag fab antibodies screened from phage antibody library. the products were cloned into puc19 vector and their sequences were analysed. the vh and vl gene fragments were tethered by a peptide linker and a leader sequence coding region, with the leader sequence added at 5 " terminus of each gene ( l - vh - linker - vl ) and designated as l - scfv
方法以從噬菌體抗體庫中篩選獲得的抗hbsag的fab抗體基因為模板，分別擴增出其輕、重鏈可變區（ v _ l 、 v _ h ）基因，通過重組pcr方法將輕、重鏈可變區基因用連接肽（ gly _ 4ser ） _ 3的編碼序列連接，並引入前導肽編碼序列，構建具有l - v _ h - linker - v _ l結構的單鏈抗體基因。 -
In genetic engneering, nonviral dna can be inserted into a phage, which is then used as a cloning vector
在基因工程中，沒有病毒的dna可以被插入到噬菌體中，用作克隆載體。
