从头基因和基因组合成可以设计任何序列,而无需像传统基因工程方法那样需要预先存在的模板。大规模生产合成基因的能力为生物学研究带​​来了巨大潜力,但从头 DNA 构建体的广泛应用目前因其高成本而受到阻碍。在这项工作中,我们描述了一种用于平行固相合成寡核苷酸的微流控平台,该平台可以通过减少试剂消耗(100倍)来大大降低基因合成的成本,同时保持〜100 pmol的合成规模,因此在组装之前无需扩增。在此平台上平行合成了 16 个寡核苷酸,然后成功用于连接介导的组装方法,生成长度约 200 bp 的 DNA 构建体。
De novo gene and genome synthesis enables the design of any sequence without the requirement of a pre-existing template as in traditional genetic engineering methods. The ability to mass produce synthetic genes holds great potential for biological research, but widespread availability of de novo DNA constructs is currently hampered by their high cost. In this work, we describe a microfluidic platform for parallel solid phase synthesis of oligonucleotides that can greatly reduce the cost of gene synthesis by reducing reagent consumption (by 100-fold) while maintaining a ∼100 pmol synthesis scale so there is no need for amplification before assembly. Sixteen oligonucleotides were synthesized in parallel on this platform and then successfully used in a ligation-mediated assembly method to generate DNA constructs ∼200 bp in length.
