How to make 10 mM dNTP Mix?
How to make 10 mM dNTP Mix?
So the correct method to make a 10 mM dNTPs is mixing as below,
- 1 microliter 100 mM dATP.
- 1 microliter 100 mM dGTP.
- 1 microliter 100 mM dCTP.
- 1 microliter 100 mM dTTP.
- 36 microliter H2O.
- Because, now you have 400 mM dissolved in 40 microliter total volume, 400 mM/40 = 10 mM dNTP mix.
What are dNTPs used for?
dNTP stands for deoxyribose nucleotide triphosphate employed in PCR to expand the growing DNA strand. dATP, dTTP, dGTP and dTTP are four common dNTPs used in PCR. The function of dNTPs in PCR is to expand the growing DNA strand with the help of Taq DNA polymerase.
What is a dNTP Mix?
dNTP Mix is a solution containing sodium salts of dATP, dCTP, dGTP and dTTP, each at 10mM in water at pH 7.5; the total concentration of nucleotides is 40mM. One microliter of the dNTP Mix in a 50μl reaction will give a final dNTP concentration of 200μM for each dNTP.
What is dNTP solution?
Deoxynucleotide (dNTP) Solution Mix is an equimolar solution of ultrapure dATP, dCTP, dGTP and dTTP. A small pack contains 4 vials of 0.2 mls and a large pack contains 5 vials of 0.8 mls. Supplied in: Ultrapure water as a sodium salt at pH 7.5.
What are the recommendations for the stability of dNTP?
Recommendations 1 Greater than 99% purity confirmed by HPLC 2 Free of human and E. 3 Highly stable 4 Stable for years at -20°C 5 Stable after multiple freeze-thaw cycles 6 Up to 95% of dNTPs remain in triphosphate form even after 7 weeks at room temperature
What is dNTP mix made of?
Thermo Scientific dNTP Mix contains premixed aqueous solutions of dATP, dCTP, dGTP and dTTP, each at a final concentration of 10 mM. The nucleotides have greater than 99% purity, are free of nuclease activities, human and E. coli DNA.
What is the concentration of dNTP in a PCR mixture?
Each nucleotide is present at a concentration of 10 mM in the mixture for a total dNTP concentration of 40 mM. 7-deaza-dGTP is a useful additive for the PCR of GC-rich templates; contains a 5 mM solution of 7-deaza-dGTP as a dilithium salt.
