Q:PCR Mix 可以用于 PAGE 电泳吗?
A:不建议,PCR Mx 中含有影响 PAGE 胶电泳的组分。推荐客户使用 10101
Q:PCR Mix 可以减少体系么?
A:可以,使用的引物、模板等比减少使用。
Q:10102 和 10103 有什么区别?
A:区别在于 10102 预混有溴酚蓝指示剂。后续可直接进行凝胶电泳。而 10103 中无溴酚蓝指示剂,电泳时需要添加DNA loading buffer。
Q:扩增完送测序。应选有染料的还是无染料?
A:都可以。PCR 产物测序,测序公司会先进行纯化。
Q:10102 镁离子浓度,dNTP 浓度分别是多少?
A:镁离子终浓度 2mM,200 µM of each dNTP。
Q:PCR Mix 扩增完成后,可以直接做酶切吗?
A:不建议,某些组分可能会影响酶切效果。
Q:PCR Mix 有没有 3’-5’的外切酶活性?PCR Mix 扩增产物类型?
A:没有 3’-5’的外切酶活性,产物带有 3’-A。可用于TA 克隆。
