    • PROBLEM TO BE SOLVED: To provide methods and compositions for in vitro amplification of nucleic acids which is useful for increasing the number of copies of a nucleic acid sequence to provide sufficient copies to be readily detected.SOLUTION: The present invention provides compositions that include one or more target-specific universal (TSU) oligonucleotide primers that include both a target-specific sequence and a universal sequence in the same oligonucleotide. The TSU primers include at least one TSU promoter primer oligonucleotide made up of a 5' promoter sequence, a first internal universal sequence (U1) and a first 3' target specific sequence (TS1) that binds specifically to a target specific sequence (TS1) that binds specifically to a target sequence contained in a target nucleic acid. Such compositions may further include at least one TSU non-promoter primer oligonucleotide made up of a second 5' universal sequence (U2) and a second 3' target specific sequence (TS2) which is different from the TS1.
    • 要解决的问题:提供用于体外扩增核酸的方法和组合物,其可用于增加核酸序列的拷贝数以提供足够的拷贝以容易地检测。解决方案:本发明提供了包含一个 或更多的靶特异性通用(TSU)寡核苷酸引物,其包括相同寡核苷酸中的靶特异性序列和通用序列。 TSU引物包括由特异性结合靶特异性序列(TS1)的5'启动子序列,第一内部通用序列(U1)和第3'靶特异性序列(TS1)组成的至少一个TSU启动子引物寡核苷酸, 其特异性结合靶核酸中包含的靶序列。 这样的组合物可以进一步包括由与TS1不同的第二个5'通用序列(U2)和第二个3'靶标特异性序列(TS2)组成的至少一个TSU非启动子引物寡核苷酸。
