400μM of each dNTP was used with 10nM primer-template and reactions were initiated by adding the polymerase to a final concentration of 500nM. Subsequently 40μl aliquots were sampled at appropriate time-points by quenching with an equal volume of stop buffer (95% formamide, 10mM EDTA, ...
The existence of spatial location is to distinguish rNTPs and dNTPs. It is well known that the concentration of rNTPs in cells is about ten times that of dNTPs. In order to ensure that only dNTPs participates in the reaction, rNTPs is excluded from the reaction. Here, compared with dNTPs...
3. Dilute the DNA samples to the required concentration for sequencing. Library Preparation 1. Fragment the DNA samples using sonication or enzymatic digestion. 2. End repair and A-tailing of the DNA fragments. 3. Adapter ligation to the DNA fragments. 4. PCR amplification of the DNA library...
Coli competent cells, all of the transformation mixtures was spread in one LB plate containing ampicillin with the final concentration of 50 μg/mL. As expected, around one hundred and fifteen colonies were observed from one LB plate (Fig. 3D). Next, we inoculated 5 mL LB medium by ...

3. optimize reactants concentration a. magnesiom ions Mg2+离子的作用主要是 dNTP-Mg 与核酸骨架相互作用 并能影响 Polymerase 的活性,一般的情况下 Mg2+的浓度在 0.5-5 mM 之间调整,同样要记住的是在调整了 dNTPs 的浓度后要相应的调整 Mg2+离子的浓度,对实时定量 PCR,使用 3 到 5 mM 带有荧光探针的镁...
for Taq's polymerization activity. It is important to note that there are other substrates in PCR amplifications that can also bind free magnesium (such as primers and template) therefore, the magnesium ion concentration should be titrated in order to find the optimum concentration for each ...
