A set of 4 dNTP contains 4 tubes of dNTPs solutions at a concentration of 100 mM (Cat.-No. 110011 and Cat.-No. 110012) or with the concentration of 20 mM (Cat.-No. 110031 and Cat.-No. 110032).
Each particular dNTP is tested for purity ( > 98% HPLC), UV-spectral characteristics, NMR-characteristics, the performance in PCR with Taq DNA Polymerase and Pfu DNA Polymerase, the absence of deoxyendo-/exonucleases and RNase activities in appropriate tests.
