Principle

HotStarTaq Plus DNA Polymerase具备同HotStarTaq DNA Polymerase一样的卓越表现,激活时间只需5分钟。

 HotStarTaq Plus DNA Polymerase,是一种经修饰的QIAGEN Taq DNA Polymerase,以非活性形式提供,常温下没有聚合酶活性。避免PCR构建和循环初始阶段低温条件下非特异性引物的延伸和引物二聚体的形成(参见"

QIAGEN PCR Buffer

QIAGEN PCR Buffer通过提高每个PCR扩增退火过程特异性引物的结合比例,确保PCR每个循环特异性扩增(参见" Increased specificity of primer annealing")。独特的KCl和(NH4)2SO4平衡组合,使得该缓冲液与传统的PCR缓冲液相比在很宽的温度和Mg2+浓度范围内都有严格的引物退火条件和高度的特异性,无需进行耗时的优化。

CoralLoad PCR Buffer

HotStarTaq Plus DNA Polymerase同时提供CoralLoad PCR Buffer,CoralLoad PCR Buffer具备QIAGEN PCR Buffer的所有优点,同时可直接将PCR产物上样到琼脂凝胶上,无需加入凝胶上样缓冲液。CoralLoad PCR Buffer具备同样高的PCR特异性,与常规的QIAGEN PCR Buffer一样可减少优化过程。此外,它包含两种指示染料,橙色染料和红色染料,可方便的判断DNA的迁移距离和优化跑胶时间(参见" CoralLoad PCR Buffer")。该缓冲液提高移液的可见性,并可直接将PCR产物上样至凝胶,提高便利性。

Q-Solution

该产品同时提供Q-Solution,一种新型的PCR添加剂,通过修饰DNA熔解行为促进难扩增模板的扩增。这种独特的试剂可进一步优化由模板引起的表现不理想的PCR,如过多的二级结构和富含GC的模板(参见" Amplification of difficult templates")。不同于DMSO和其他PCR添加剂,Q-Solution的浓度是确定的,没有毒性,并且保证PCR的纯度。而且PCR中加入Q-Solution不会影响PCR的准确性。
