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。Thus, immunologists have sought smaller molecules with the antigen - recognition capability of antibodies. the variable domains of the heavy ( h ) and light ( l ) chains are sufficient for antigen recognition but the non - covalent complex of the two variable domains ( fv ) is unstable. it is possible to genetically engineer a single - chain fv ( scfv ) with the h chain v region connected to the l chain v region via a 15 amino acid linker composed of serine and glycine amino acid residues
二、日本血吸蟲單克隆杭獨特型抗體np30的單鏈狐（ scf ）的構建、表達及對balbic小鼠誘導保護性作用研究l 、日本血吸蟲單克隆杭獨特型抗體np0的單鏈抗體歸cfv ）的構建、表達通過pcr方法體外擴增並經測序驗證的重鏈、輕鏈可變區（ vh 、 vl ）基因先後重組入原核表達質粒ptha90相應的位點上，中間通過一連接肽（ gly在er ） 。This is important in attempting to use antibodies as anti - tumor reagents, for example
基因為日本血吸蟲單克隆抗獨特型抗體np30輕鏈和重鏈可變區基固。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。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
應用重組噬菌體抗體庫技術，從分泌小鼠抗牛精子sp18抗體的雜交瘤細胞系中分離總rna ，克隆抗體重鏈和輕鏈可變區基因，加入連接肽引物（ linkerprimer ）組裝成單鏈抗體scfv （ singlechainfragmentvariable ）基因並用rs引物進行擴增， sfi 、 not酶切，回收后與pcantab5e載體相連，轉化e . colitg1宿主菌，構建單鏈抗體文庫。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。分享友人
