一般描述
JumpStart™ AccuTaq™ LA DNA聚合酶是Sigma的高保真混合物、AccuTaq长链高保真(LA) DNA聚合酶和Taq中和JumpStart Taq抗体的组合。这种特殊配制的酶是长链高保真PCR、多重PCR以及可变长度靶点PCR扩增的最佳选择,如cDNA库扩增。JumpStart Taq抗体可逆结合AccuTaq LA DNA聚合酶,在室温下失活。第一个变性循环的温度升高,使复合物解离,恢复酶的活性。与标准扩增相比,这种热启动机制提供了更高的特异性和更高的目标良率。
应用
JumpStart™ AccuTaq™ LA DNA聚合酶已用于:
- 放大土壤DNA样品的聚合酶链式反应(PCR)
- 组蛋白H2A.Z的精确长范围PCR,细菌人工染色体(BAC)
- 作为PCR反应混合物的成分,通过常规PCR扩增病毒DNA
特点和优势
- JumpStart AccuTaq LA DNA 聚合酶是一种抗体失活的热启动酶,旨在最大限度地减少非特异性扩增,同时提高目标产量和特异性
- 保真度比 Taq DNA 聚合酶高 6.5 倍,使其成为多重 PCR 的首选酶
- 使用基因组模板产生高达 22 kb 的扩增子,使用不太复杂的模板(如 λ 或细菌基因组 DNA)产生高达 40 kb 的扩增子
- 减少设置时间,并消除与手动或蜡热启动方法相关的问题
包装
提供 10× 反应缓冲液。
单位定义
在 74℃ 下一个单位在 30 min 内将 10 nmol 的总 dNTP 掺入到酸可沉淀的 DNA 中。

Long and accurate PCR applications address the needs for longer read lengths, greater fidelity and higher yields than that which can be achieved with Taq DNA polymerase.
The purpose of Hot Start PCR is to inhibit the PCR reaction in order to reduce nonspecific amplification, prevent the formation of primer dimers, and increase product yields.
热启动PCR的目的在于抑制PCR反应,从而减少非特异性扩增、防止引物二聚体形成并提高产物产量。
实验方案
