一般描述

核苷酸是有机分子,可作为核酸(如DNA和RNA)的单体或亚基。核苷酸是核酸的结构单元,由一个含氮碱基(嘌呤或嘧啶)、一个五碳糖(核糖或脱氧核糖)和至少一个磷酸基团组成。一个核苷与一个磷酸基团组合形成一个核苷酸。脱氧核苷酸混合物是一种便捷式预混dNTP溶液,以高质量分子生物学级水为溶剂,含有等摩尔(10mM)的UltraPure超纯dATP、dCTP、dGTP和TTP钠盐。1 µL足够进行一次标准50 µL PCR反应。

应用

dNTP混合物已用于:

  • PCR扩增昆虫、 真菌、病毒、人类来源分离的基因组DNA
  • 总RNA逆转录为cDNA
  • 作为聚合酶链式反应(PCR)DNA扩增混合物组分
  • 常规和长片段PCR
  • 手动和自动DNA测序
  • cDNA合成和标记反应

特点和优势

  • 每种dNTP的纯度:最低99%
  • 方便配制;每50 μL PCR使用1 μL
  • 等摩尔量的各种dNTP可减少移液步骤
  • 最大限度地降低PCR污染风险
  • UltraPure超纯dNTP可帮助最大限度地提高关键PCR反应的一致性和得率
