Enzyme reagent SMOChem™

solutionfor PCRfor DNA amplification

Ultrapure dUTP (2´-Deoxyuridine, 5´-Triphosphate) supplied as sodium salt in purified water (pH 8.5). dUTP can be used in place of dTTP in PCR and RT-PCR protocols to prevent carryover from previous amplifications. The substitution of dUTP for dTTP in PCR results in uracil-containing PCR products that are suitable for most standard applications. The enzyme uracil-N-glycosylase (UNG, also referred to as UDG) can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives. Each lot of dUTP is tested to ensure specific DNA amplification and the absence of nuclease activity. Features Ideal for PCR amplification and cDNA synthesis Nuclease and ribonuclease free Applications Avoid carryover contamination between PCRs to eliminate a source of false positives. Preparation Note Working solution: We recommend to prepare a deoxynucleotide mix containing dATP, dCTP, dGTP (10 mM, each), dUTP (20 mM); (e.g., for the preparation of 100 μl nucleotide mix add 10 μl of dATP, dCTP, dGTP (each) and 20 μl dUTP to 50 μl water, PCR grade).
