| 4. | 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 取阳性重组噬菌体抗体克隆株pcsa1 , pcr扩增其scfv基因,筛选重组子进行序列测定,发现其序列符合小鼠抗体基因的一般特征,并且与几株抗磷酸胆碱的抗体重链和轻链可变区序列的同源性达80以上;推测pcsa1scfv针对的抗原是磷酸胆碱类物质。 |
| 5. | The library consisted of 1 . 3 x 106 clones with an average insert size of about 18kb . the capacity of this library was about 20 times the equivalent of the genome of atriplex centralasiatica iljin . screening the genomic library with a 400bp probe located at the 5 ' end of the badh gene obtained by rt - pcr , we got four positive clones 3x10 ‘个重组噬菌体,插入片段大小约为18kb ,含插入片段的频率为100队以中亚滨蓉甜菜碱醛脱氢酶门adh )基因近5 ’端的约400hp片段为探针,筛选中亚滨蓉基因组文库,得到了4个阳性克隆。 |
| 6. | Detection of antigen - binding affinity of mg7 recombinant phage antibody elisa was repeated to confirm the antigen - binding affinity of positive clones screened out in the former procedure ; these positive phages were examined by restriction analysis ( ecor i and hind iii ) ; competitive elisa was performed to test the inhibitory ratio of these positive clones to the binding affinity of mg7mab and its relevant antigen , the positive dones possessing apparent inhibitory effect were singled out for later use X阳性克到驶知烘扳原kbbjg )浊对阳性克隆进行限制陇卧赐析( uwi和hedlll )鉴定三用竞争elisatoljmg7重组噬菌体抗体性克隆对mg7单扶与其相应抗原结合忙的喇率,从中j ) ed出对mg7单抗与期眩抗原结合有抑余j效应的克隆用于进一涉研究。 |
| 7. | Panning and enrichment ofmg7 recombinant phage antibody the transformed cells were infected with m13k07 helper phage to produce a phage form of mgy recombinant phage antibody library ; after three rounds panning of the library with the mgrbinding antigen highly expressed gastric cancer cell line kato iii , the mg7 scfv displayed phage dones were selected from the enriched recombinant phages by elisa 3 mg _ 7重组噬菌体抗体库的淘筛用m13ko7辅助噬菌体感染转化菌,以挽救出噬菌体形式的抗体库;用高表达mg _ 7抗原的胃癌细胞系kato对抗体库进行三轮淘筛;用elisa筛检呈现有mg _ 7scfv的噬菌体单克隆。 |
| 8. | In the present study , the express library of monoclonal anti - sp18 scfv ( single chain fragment variable ) gene is constructed and selected for further study of sp18 antigen on mammalian fertilization and embryogenesis . total rna were firstly isolated from these growing hybridoma cells which secretes monoclonal anti - sp18 antibodies . after obtained using rpas system , vh and vl genes were used to assemble scfv gene fragment with a linker primer 应用重组噬菌体抗体库技术,从分泌小鼠抗牛精子sp18抗体的杂交瘤细胞系中分离总rna ,克隆抗体重链和轻链可变区基因,加入连接肽引物( linkerprimer )组装成单链抗体scfv ( singlechainfragmentvariable )基因并用rs引物进行扩增, sfi 、 not酶切,回收后与pcantab5e载体相连,转化e . colitg1宿主菌,构建单链抗体文库。 |
| 9. | 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重组噬菌体抗体库的构建及鉴定从培养的mg _ 7杂交瘤细胞中提取并分离mrna ,反转录成cdna ;利用pcr分别扩增mg _ 7单抗的重链及轻链可变区基因,并通过? dna连接子将二者连接起来形成mg _ 7单链抗体基因;将mg _ 7单链抗体基因插入pcantab5e ;将连接产物转化感受态tg1大肠杆菌,制备细菌形式的mg _ 7重组噬菌体抗体库;通过菌落计数和限制性酶切分析( ecor和hind )评估mg _ 7重组噬菌体抗体库的容量和重组率。 |
