Objective To develop a high sensitivity and reproducible method for rapid DNA analysis even when using picogram sample in a complex background. 目的建立一种灵敏度高、重现性好的检测混合样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. “我们不仅能检测皮克水平-100亿分之一克蛋白，而且也可以看到的蛋白质修饰方式上的非常微妙变化。
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. 本发明核酸检测灵敏度可达0.
