    • The present invention provides a process for preparing a ready-to-use reagent for PCR, which comprises the steps of adding the stabilizer, glucitol or glucose, to an aqueous polymerase chain reaction(PCR) mixture containing a reaction buffer, MgCl.sub.2, dNTPs, a DNA polymerase, the water soluble dye, bromophenol blue, xylene cyanole, bromocresol red or cresol red, a primer, and optionally, ddATP, ddCTP, ddGTP, or ddTTP, and then lyophilizing thereof. The ready-to-use PCR reagent of the present invention leads to a simplification of multi-step PCR manipulation, an increase of heat stability of the reaction mixture, prevention of carry-over contamination, and improved credibility of experiments. The ready-to-use PCR reagent can be applied as a kit for analysis of DNA sequence or for diagnosis of diseases.
    • 本发明提供了一种制备用于PCR的即用试剂的方法,其包括将稳定剂,葡萄糖醇或葡萄糖添加到含有反应缓冲液,MgCl 2,dNTPs的水性聚合酶链式反应(PCR)混合物的步骤中, DNA聚合酶,水溶性染料,溴酚蓝,二甲苯氰,溴甲酚红或甲酚红,引物,以及任选的ddATP,ddCTP,ddGTP或ddTTP,然后冻干。 本发明的即用型PCR试剂简化了多步PCR操作,提高了反应混合物的热稳定性,防止了携带污染,提高了实验的可信度。 即用型PCR试剂可用作DNA序列分析或疾病诊断的试剂盒。
