Objective To develop a high sensitivity and reproducible method for rapid DNA analysis even when using picogram sample in a complex background. 目的建立一種靈敏度高、重現(xiàn)性好的檢測(cè)混合樣品中微量目的基因的方法。

"Not only can we detect picogram levels -- one-trillionth of a gram -- of protein, but we can also see very subtle changes in the ways the protein is modified. “我們不僅能檢測(cè)皮克水平-100億分之一克蛋白，而且也可以看到的蛋白質(zhì)修飾方式上的非常微妙變化。

The present invention can reach a nucleic acid detecting sensitivity up to 0.1 picogram, and the gene chip signal detecting kit may be further developed. 本發(fā)明核酸檢測(cè)靈敏度可達(dá)0.
