DNA microarrays provide a natural vehicle for this exploration. The model organisms are the first for which comprehensive genome–wide surveys of gene expression patterns or function are possible.

PCR is one of the technologies poised to turn microarray discoveries into more in-depth, targeted studies.

The rising prevalence of cancer worldwide, increasing adoption of minimally invasive diagnostic tests, and advances in ...

这篇研究开发了8种PCR阻断引物（blocking primers），通过抑制海七鳃鳗（Petromyzon marinus）12S rRNA基因扩增，显著提升宿主鱼类DNA在宏条形码（DNA metabarcoding）饮食分析中的检出率。该技术突破传统方法限制，为血食性物种的分子饮食研究提供了高效工具。
