dUTP solution 100mM

Deoxyuridine 5'-triphosphate, tetrasodium salt (dUTP) of purity >99% (HPLC). dUTP may be used in place of dTTP in PCR and RT-PCR protocols to prevent carryover from previous amplifications. Product has been tested for PCR products of length up to 8kb (Taq DNA polymerase) and 0.8kb (Pfu DNA polymerase). The substitution of dTTP for dUTP in PCR results in uracil-containing PCR products that are suitable for most standard applications. The enzyme Uracil-DNA-Glycosylase, UDG >, can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives.
