产品简介:
                                    SYBR Green I, is a very sensitive dye for the detection of double stranded DNA (dsDNA), So it  has been widely used in non-specific detection of amplification in realtime qPCR experiments. The double-strand DNA-specific SYBR Green I fluorescent reporter offers distinct advantages. SYBR Green I dye is inexpensive, easy to use, and sensitive. Well-designed primers must be used in SYBR Green quantitative RT-PCR reactions because SYBR Green I dye will detect nonspecific products, resulting in an overestimation of the target concentration.
                                操作步骤:
                                    1、On ice, prepare a 2x master mix containing no DNA, by mixing the components in the following order: water,DMSO, Taq polymerase buffer, dNTPs, MgCl2, Sybr Green, Taq polymerase.
2、Transfer 2x QuantiTect SYBR Green PCR Master Mix to tubes or plates. Add RNase-free water. Mix the individual solutions.
3、Prepare a reaction mix according to Table 2.Due to the hot start, it is not necessary to keep samples on ice during reaction setup or while programming the real-time cycler.
PCR Reaction Setup: Table 2:
DNA:Template DNA (<500 ng/reaction)
SYBR Mix:25.0 μL
Primer1(引物1):2ul(5uM)
Primer2(引物2):2ul(5uM)
dd H2O:Added to 50.0 μL
Program your real-time cycler according to the program outlined in Table 3
PCR initial activation step: Heating cycling Number of cycles 40
95 °C 5min: 96 °C 10s,60 °C 30s
附件:
SUPER Green I与dsDNA 结合荧光信号可增强800~1000倍。在PCR反应体系中,加入过量SUPER Green I荧光染料,它特异性地掺入DNA双链后,荧光信号增强,而不掺入链中的SUPER Green I染料分子荧光不变,从而保证荧光信号的增加与PCR产物的增加完全同步。荧光可以在退火阶段或者延伸阶段测定。
1.使用浓度对荧光PCR结果的影响
SUPER Green I的使用浓度是保证荧光定量PCR实验成功非常关键的因素。如果SUPER Green I的浓度过低会使荧光信号的变化降低,这就意味着低拷贝的样品可能无法检出。而在高浓度时,将会抑制PCR反应,降低PCR反应效率。所以一般在使用SUPER Green I时应根据实际情况优化使用浓度,反应的终浓度为1×到0.2×之间。
2.Mg2+浓度的影响
提高Mg2+浓度可以降低SUPER Green I对PCR反应的抑制作用。我们建议在用SUPER Green I进行荧光PCR反应时,Mg2+浓度比无SUPER Green I 的普通 PCR 反应高出0.5-3mM。
                                2、Transfer 2x QuantiTect SYBR Green PCR Master Mix to tubes or plates. Add RNase-free water. Mix the individual solutions.
