So Oxford Nanopore has also been looking at an alternative approach, called exonuclease sequencing, in conjunction with Illumina, an American firm that is the market leader in rapid sequencing.

所以“牛津纳米孔公司”，和快速测序领域的领头羊，“Illumina公司”也在一同研究一种叫做“核酸外切酶测序”的办法。

Both sides have been helped by a technical development, the construction by companies like Affymetrix and Illumina of instruments known as microarrays or chips that can now detect up to 500,000 snips.

技术进步给两面都带来了极大的帮助。像Affymetrix和Illumina构建公司的微阵列或芯片工具现在已能检测到50万个SNP。
