UltraPure级及mNGS级dNTP来啦！
dNTP，即Deoxy-ribonucleoside triphosphate，中文名为脱氧核糖核苷三磷酸，包括dATP (脱氧腺苷三磷酸)、dCTP (脱氧胞苷三磷酸)、dGTP (脱氧鸟苷三磷酸)、dTTP (脱氧胸苷三磷酸)、dUTP (脱氧尿苷三磷酸)等。其中，dATP、dCTP、dGTP和dTTP作为PCR反应的原料，在PCR体系中不可或缺，在PCR延伸环节中，基于碱基互补配对的原则与模板链结合，在聚合酶的作用下合成新的DNA链，其质量及浓度与PCR反应的扩增效率密切相关。
碧云天生产的dNTP (UltraPure, ≥99.8%)和dNTP (mNGS grade, ≥99.8%)是采用超纯的dATP、dCTP、dGTP、dTTP和dUTP配制的单组分或混合溶液，适合用于需要高纯度dNTP的PCR、real-time PCR、RT-PCR、cDNA或普通DNA合成、引物延伸反应、DNA测序、DNA标记等各种常规分子生物学反应，其中dNTP (mNGS grade, ≥99.8%)专为mNGS测序、高度扩增的高通量测序、LAMP、多重扩增等对dNTP要求较高的PCR反应所设计。
本dNTP (UltraPure, ≥99.8%)系列产品均不含DNase、RNase、缺刻酶(Nickase)和蛋白酶；
本dNTP (mNGS grade, ≥99.8%)系列产品均不含DNase、RNase、Phosphatase、切口酶和蛋白酶，无E.coli DNA、人基因组DNA、mNGS背景核酸污染。
