乙酰脲

We establish a microtechnique developed from cytochrome C spreading methods allowing the detection of minimal amounts of DNA through a calibrated composition of buffer、denaturing agents and cytochrome C in an extremely small volume of spreading mixture.

将变性剂脲、乙二醛、甲酰胺引入展开过程，我们在国内首次建立了可检测1×10〓--2×10〓ug以下量DNA样本的微量展层技术，能较好地展开dsDNA及ssDNA分子，DNA形态及长度与经典技术所制样本相似。
