应将干粉和溶解的引物储存在-20°Co以大于10uM浓度溶于TE的 引物在-20笙可以稳定保存6个月,但在室温(15T到3(TC)仅能保存不到1周。干粉引物可 以在-2CTC保存至少1年,在室温(15乜到30X:)最多可以保存2个月。 3.optimize reactants concentration a.magnesiom ions Mg离子的作用主要是dNTP-Mg与核酸骨架...
Additional file 3: Additional Figure 2 - Evaporation rate curve. Evaporation rates were measured with an MMV filled with water placed on ice (square) or on the lab bench (triangle) under the conditions of room temperature (~15°C) and humidity (47% and 58%, respectively). (PDF 21 KB)...

However, PCR is known to introduce biases during amplification, particularly during multiplex PCR when several templates are amplified simultaneously [1, 2]. Extreme base compositions (sequences with mostly G/C or A/T composition) are recognized to be problematic for both traditional Sanger ...
在1987年,第一款商品化的热循环仪,来自Perkin Elmer Cetus的TC1 DNA热循环仪面世,通过使用金属模块因而具备了对样品进行程序性加热和冷却的能力(图1)。在1988年,在TC1热循环仪中第一次使用热稳定性酶--TaqDNA聚合酶的情况被报道[2]。 这为将PCR应用...
2、引物GC含量 GC含量在40%－60%之间，以45-55％为宜。这可为有效退火提供足够热。引物设计的原则 3、引物Tm 引物所对应模板序列的Tm值最好72℃左右。至少要在55－80℃之间。Tm=2(A+T)+4(C+G)引物设计的原则 4、引物3’端 ••••引物3’末端和模板的碱基完全配对防止一对引物内的同源性考虑...
