探针。荧光染料可以是Cy3、Cy5、FITC、fluorescein、Texas red、rhodamine、bodipy或者Alexa dye,而且各种荧光染料的标记效率相当。值得一提的是这种间接荧光标记比直接标记法的效率更高,在双色荧光标记时,可以避免直标法因为Cy5标记效率低而导致Cy3、Cy5两种颜色信号强度不同的现象。试剂盒提供除荧光染料外的全部试剂,足够作10次标记。 6)Vysis公司的Microarray Nick Translation Kit 是配合Vysis公司
,最终整合杂交点的生物学信息,发现基因的表达谱与功能可能存在的联系。 Microarray数据分析主要包括图象分析(Biodiscovery Imagene 4.0\Quantarray分析软件)、标准化处理(normalization)、Ratio值分析、基因聚类分析(Gene Clustering)。 1. 图象分析:激光扫描仪Scaner得到的Cy3/Cy5图象文件通过划格(Griding),确定杂交点范围,过滤背景噪音,提取得到基因表达的荧光信号强度值,最后以列表形式输出
