Direct label probe compositions which stain DNA of a preselected single chromosome or region of a chromosome of a multi-chromosomal genome are provided that comprise mixed DNA segments which are covalently bound to fluorophore groups through linking groups. The mixed DNA segments are derived from the DNA present in the preselected chromosome or chromosome region. These probe compositions can be used concurrently or sequentially with other probe compositions.
直接标记探针组合物可对多染色体
基因组中预选的单条染色体或染色体区域的 DNA 进行染色,该组合物由混合 DNA 片段组成,这些 DNA 片段通过连接基团与荧光团共价结合。混合 DNA 片段来自预选染色体或染色体区域中的 DNA。这些探针组合物可与其他探针组合物同时或依次使用。
