    • Disclosed are methods for identifying nucleic acid sequences which are of different abundances in different nucleic acid source populations, e.g. differentially expressed genes or genomic variations among individuals or populations of individuals. In one embodiment, probes derived from the source nucleic acid populations are derivatized with a terminal sample ID (SID) sequence characteristic of that population. Upon competitive hybridization of the probes to a reference or index nucleic acid library containing all the sequences in the populations being compared, the SID tags remain single stranded, and those from the different sources are then annealed to one another. Unhybridized (remainder) SID sequences are then quantified. By labeling such remainder SID sequences with a fluorescent dye, FACS sorting of beads containing the hybridized probes can be carried out. The signal ratio upon which such sorting is based is enhanced compared to competitive hybridization using labeled probes without SID sequences.
    • 公开了用于鉴定在不同核酸源群体中具有不同丰度的核酸序列的方法,例如, 差异表达基因或个体个体或个体群体的基因组变异。 在一个实施方案中,衍生自源核酸群体的探针用该群体特征的终端样品ID(SID)序列衍生化。 当探针与包含正在比较的群体中的所有序列的参考或指数核酸文库竞争性杂交时,SID标签保持单链,然后来自不同来源的那些序列彼此退火。 然后对未杂交(其余)SID序列进行定量。 通过用荧光染料标记这些剩余的SID序列,可以进行含有杂交探针的珠的FACS分选。 与使用没有SID序列的标记探针的竞争性杂交相比,这种分选所基于的信号比率增加。

    • The invention provides a method and materials for monitoring and isolating differentially expressed genes. In accordance with the method of the invention, differently labeled populations of DNAs from sources to be compared are competitively hybridized with reference DNA cloned on solid phase supports, e.g. microparticles, to provide a differential expression library which, in the preferred embodiment, may be manipulated by fluorescence-activated cell sorting (FACS). Monitoring the relative signal intensity of the different fluorescent labels on the microparticles permits quantitative analysis of expression levels relative to the reference DNA. The invention also provides a method for identifying and isolating rare genes. Populations of microparticles having relative signal intensities of interest can be isolated by FACS and the attached DNAs identified by sequencing, such as with massively parallel signature sequencing (MPSS), or with conventional DNA sequencing protocols.
