Abstract

ELISAs provide a valuable tool in the detection and diagnosis of virus infection. The ability to produce recombinant viral proteins will ensure that future ELISAs are safe, specific and rapid. This latter point being the most crucial advantage in that even if a virus cannot be cultured, provided gene sequence is available, it is possible to rapidly respond to emerging viruses and new viral strains of existing pathogens. Indeed, ELISAs based on peptides (corresponding to epitopes) also hold great promise, as in this case no cloning or expression of a recombinant protein is required. Both recombinant protein and peptide based systems lend themselves to large scale production and purification. These approaches can also be used to distinguish recombinant vaccines from parental or wild type viruses.

摘要

酶联免疫吸附测定(ELISA)为病毒感染的检测与诊断提供了一种有价值的工具。生产重组病毒蛋白的能力将确保未来的ELISA检测安全、特异且快速。后一点是最为关键的优势,因为即便一种病毒无法培养,但只要有基因序列,就有可能对新出现的病毒以及现有病原体的新病毒株做出快速反应。实际上,基于肽段(对应于表位)的ELISA也很有前景,因为在这种情况下无需克隆或表达重组蛋白。基于重组蛋白和肽段的系统都适合大规模生产与纯化。这些方法还可用于区分重组疫苗与亲本病毒或野生型病毒。
