Enhancements in sequencing technology have recently yielded assemblies of large genomes including rat, mouse, human, fruit fly, and zebrafish. The availability of large-scale genomic and genic sequence data coupled with advances in microarray technology have made it possible to study the expression of large numbers of sequence products under several different conditions in days where traditional molecular biology techniques might have taken months, or even years. Therefore, to efficiently study a number of gene products associated with a disease, pathway, or other biological process, it is necessary to be able to design primer pairs or oligonucleotides en masse rather than using a time consuming and laborious gene-by-gene method.
We have developed an integrated system, MPrime, in order to efficiently calculate primer pairs or specific oligonucleotides for multiple genic regions based on a keyword, gene name, accession number, or sequence fasta format within the rat, mouse, human, fruit fly, and zebrafish genomes. A set of products created for mouse housekeeping genes from MPrime-designed primer pairs has been validated using both PCR-amplification and DNA sequencing.
These results indicate MPrime accurately incorporates standard PCR primer design characteristics to produce high scoring primer pairs for genes of interest. In addition, sequence similarity for a set of oligonucleotides constructed for the same set of genes indicates high specificity in oligo design.
测序技术的进步最近已产生了包括大鼠、小鼠、人类、果蝇和斑马鱼在内的大型基因组组装。大规模基因组和基因序列数据的可用性,再加上微阵列技术的进展,使得在传统分子生物学技术可能需要数月甚至数年的时间里,能够在几天内研究多种不同条件下大量序列产物的表达成为可能。因此,为了有效地研究与疾病、通路或其他生物学过程相关的大量基因产物,有必要能够批量设计引物对或寡核苷酸,而不是使用耗时费力的逐个基因的方法。
我们开发了一个集成系统MPrime,以便基于大鼠、小鼠、人类、果蝇和斑马鱼基因组中的关键词、基因名称、登录号或序列fasta格式,有效地计算多个基因区域的引物对或特定寡核苷酸。使用MPrime设计的引物对为小鼠管家基因创建的一组产物已通过PCR扩增和DNA测序进行了验证。
这些结果表明MPrime准确地纳入了标准PCR引物设计特征,以产生针对感兴趣基因的高分引物对。此外,为同一组基因构建的一组寡核苷酸的序列相似性表明寡核苷酸设计具有高特异性。
