可变区基因 meaning in English
v-gene
Examples
- Cloning and expression of the variable region genes of the monoclonal antibody against human cd
16单克隆抗体可变区基因的克隆和表达 - Cloning of variable region and signal peptide genes of anti - cd20 monoclonal antibody by rlm - race
20单克隆抗体可变区基因及其信号肽基因 - 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
方法以从噬菌体抗体库中筛选获得的抗hbsag的fab抗体基因为模板，分别扩增出其轻、重链可变区( v _ l 、 v _ h )基因，通过重组pcr方法将轻、重链可变区基因用连接肽( gly _ 4ser ) _ 3的编码序列连接，并引入前导肽编码序列，构建具有l - v _ h - linker - v _ l结构的单链抗体基因。 - Methods : the rearranged gene fragment coding tcr y v region of the jurkat cell line was obtained by rt - pcr technique the pcr product was cloned into the eukaryocytic expressive vector pcdnas to construct pcdna3 / tcr y . after confirmed by sequncing . pcdnas / tcr y plasmids were amplified in bacteria extracted by alkaline lysismethod
方法：本文采用rt ? ? pcr的方法扩增jurkatt淋巴瘤细胞特异性重排的tcr可变区基因片段，克隆到真表达载体pcdna _ 3中，经序列测定无误后，碱裂解法大量提取质粒，制备dna疫苗。 - 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。
