Extra Details:: 2′-Deoxyuridine 5′-triphosphate (dUTP) may be used to study the distribution, specificity and kinetics of deoxyuridine 5′-triphosphate nucleotidohydrolase(s) (dUTPase, EC 3.6.1.23). dUTPase are important enzymes that protect cells from the incorporation of dUTP into DNA.dUTP is a component of the TUNEL (terminal deoxyribonucleotidyl-transferase-(TdT)-mediated deoxyuridine-5′-triphosphate- (dUTP) nick-end labeling) test. TUNEL is a common method for detecting DNA fragmentation that results from apoptotic signaling cascades. Applications: Suitable for use in PCR, RT-PCR with Taq DNA Polymerase, cDNA, synthesis and primer extension. Not suitable for PCR with proofreading enzymes or enzyme mixes containing proofreading enzymes. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Appearance: Supplied as a liquid in 100mM aqueous solution, pH 7.0. Purity: ≥ 99% (HPLC) Lambda Max: 262nm Endo- and Exonucleases: Incubation of single stranded and double stranded radiolabeled oligonucleotides with 1ul of 20mM dUTP for 4 hours at 37°C, separation on denaturing polyacrylamide gel and phosphoimaging did not detect DNA degradation. Ribonucleases: Incubation of 2000 base RNA transcript with 1ul of 20mM dUTP at 37°C for 4 hours and separation on agarose gel resulted in no decrease in RNA transcript band intensity compared to control. Nicking Activities: Incubation of 1ug of supercoiled pUC19 DNA with 1ul of 20mM dUTP at 37°C for 17 hours and separation on agarose gel did not generate linearised plasmid, and relaxation of supercoiled plasmid as compared to control. E.coli DNA: Quantitative PCR test on ABI Prism 7000 SDS, which uses amplification of E.coli 23S rRNA gene fragment did not detect E.coli DNA. Human DNA: Quantitative PCR test on ABI Prism 7000 SDS, which uses amplification of human genomic DNA fragment did not detect human DNA. Functional Test: PCR amplification of human apoprotein gene fragment from 50pg human genomic DNA using Hot Start Taq DNA Polymerase. Storage and Stability: Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
