Molecular Biology Grade
1. The concentration is verified by optical density spectrophotometry.
2. This preparation is free of DNase and RNase contamination as determined by incubation of the dUTP with radioactive substrates.
3. The purity of this preparation is determined by HPLC. The minimum passing specification for the triphosphate content is >99%.
4. This lot of dUTP has been performance tested with Taq DNA polymerase, Pfu DNA polymerase.
Long term (Infrequent use; 1-2 times per month): -70 C
Daily/Weekly use: -20 C
Always avoid freeze-thaw cycles or exposure to frequent temperature changes. These fluctuations can greatly alter product stability.
Note: the 100mM dUTP is not suitable for PCR with proofreading enzymes or enzyme mixes containing proofreading enzymes.
