We utilized self-cleaving peptide 2A from foot-and-mouth disease virus (FMDV 2A) connecting hIL-2 and EGFP sequence, and cloned into goat β-casein regulatory sequence, then we got mammary gland specific bicistronic expression vector pFIENβ, after transient transfection into goat mammary ...
The aim of this study was to construct mammary gland specific bicistronic expression vector based on FMDV 2A, and verify the expression of sequences of EGFP and human IL-2 in mammary epithelial cells. We utilized self-cleaving pepti...
peptide 2A from foot-and-mouth disease virus(FMDV)has a very small size,and more importantly,high cleavage activity in artifical bicistron,which bring new hope for mutiple genes therapy stategy.In this article,the characteristics and cleavage activities of FMDV 2A will be elucidated,and we ...
2A peptideTransformationExpressionThis study was the first time to express the miraculin in C. reinhardtii.The C. reinhardtii can be used to produce high-puritymiraculint, which reduces the cost.The expression vector pSP108–2A-miraculin containing 2A-miraculin fusion gene was constructed and ...
Regardless of the proximity of the foreign sequence to the cell receptor binding site (RGD motif), and the presence of highly charged residues in the foreign peptide, the FLAG substitution neither affected the virus interaction with its cognate cell receptors αvβ3 and αvβ6 integrins (Burman...
本发明公开了一种实时荧光定量RT-PCR检测FMDV群及其O型,AsiaⅠ型方法,经过对本发明所建立的方法进行了特异性,灵敏度的验证,结果显示可以较好的将FMDV同偶蹄目其他易感病毒以及O型和AsiaⅠ型区分开,且灵敏度可以达到10个拷贝数的模板用量.本发明所建立的方法整个反应过程是闭管操作,在最大程度上减少了体系的污染.从...
The G-H loop forms a major antigenic site on the virion, which includes at its apex an Arg-Gly-Asp (RGD) motif [23, 24], a sequence that has been implicated in receptor binding on the basis of synthetic peptide inhibition studies [25]. FMDV can enter cells using different pathways; ...
口蹄疫病毒(FMDV) 2A共表达抗菌肽(antibacterial peptides)是生物体内经诱导产生的一种具有生物活性的多肽,是天然免疫的重要组成部分.为了提高抗菌肽的表达量以及很方便地检测抗菌肽的表达情况,本研究利用口蹄疫病毒(Foot-and-mouth disease virus,FMDV) 2A将荧光蛋白dTomato基因和3个串联的MagaininⅡ基因融合到一个开放...
