背景情况:

固相放大 (SP-PCR) 的效率取决于固定DNA的热稳定性.
在SP-PCR中,高化温度会损害DNA的稳定性.
甲胺 (FA) 提供低温DNA变性,可能有利于SP-PCR.

研究的目的:

为了研究形式胺 (FA) 对SP-PCR中的DNA稳定性和放大效率的影响.
为优化DNA微阵列的FA变性和杂交参数.
为了比较基于FA的变性与SP-PCR中的高温变性.

主要方法:

使用交叉连接器在芯片上固定DNA.
通过FA变质的桥梁放大产生DNA微阵列.
优化FA变性和杂交参数的优化.
将FA变质与高温变质进行比较.

主要成果:

优化的FA参数实现了最大集群密度为2.83 × 10^4个殖民地/mm^2.2.
为了使FA变质,需要更低的模板度和更温和的条件,从而产生更高的集群密度.
