dna recombinant meaning in Chinese
dna重组
Examples
- However , by far , all the milk - derived antihypertensive peptides ( also known as angiotensin converting enzyme inhibitory peptides , aceips ) are produced by the proteinase hydrolysis of milk proteins , no report is available on aceips expressed by dna recombinant technology
然而，到目前为止，所有的乳源抗高血压小肽都是通过蛋白酶对乳蛋白质的水解获得的，还没有通过基因工程技术来表达抗高血压小肽的研究报道。 - Purpose 1 construction of prokaryotic high expression vector of human platelet factor 4 ( h pf4 ) 2 expression and purification of r h pf4 3 bioassay of r h pf4 methods according to the modulation character of eukaryotic protein expression in prokaryotic cells , we design a pair of particular primers , and construct a prokaryotic expression vector pbv220 - r hpf4 by dna polymerase chain reaction ( pcr ) and dna recombinant technic . the expression plasmid was identified with pcr and dna sequencing . pbv220 - r hpf4 was transformed into e . coli dh5a , bl21 ( de3 ) and induced by increasing the temperature to 42 . we identified the expression protein by sds - page and western - blotting
目的1人血小板因子4 ( hpf4 )原核高效表达克隆的构建2重组hpf4的表达及分离、纯化工艺研究3重组hpf4的特性研究方法根据原核细胞表达真核蛋白的基因表达调控特点，设计合成一对特异引物，在pt7 - 7 - rpf4表达质粒的基础上，应用聚合酶链式反应( pcr )对其cdna进行改造，通过dna重组技术构建成重组hpf4原核表达质粒pbv220 - rhpf4 ，用快速pcr检测法、 dna测序分析，鉴定重组hpf4表达质粒的正确性。
