A T C G U 100 mM, by Liters SMOBIO's dNTPs are enzymatically synthesized and undergo stringent purification steps to eliminate impurities and PCR-specific inhibitors such as modified nucleotides, tetraphosphates and pyrophosphates commonly observed in other commercially available dNTP products. SMOBIO offers greater than 99% purity of dNTPs to yield optimal results. Specification Product Name Cat.

A T C G U 100 mM, by Liters SMOBIO offers greater than 99% purity of dNTPs to yield optimal results. dATP (A) High fidelity DNA polymerase dNTP purity dNTP purity dNTP purity dNTP purity Impurity or residual PCR inhibitors in dNTP mix suppress DNA amplification. (A) High fidelity DNA polymerase, which is highly sensitive to PCR inhibitors, was completely failed in amplification using dNTP mix from other supplier. DNA amplification using Taq DNA polymerase and dNTP mix from other supplier was slightly reduced compared to dNTP mix from SMOBIO. (B) Varied purity of dNTP mix was tested with different...
