T90 | 0-4 | Sentence | denotes | 1.3. |
T91 | 5-40 | Sentence | denotes | Multiple Displacement Amplification |
T92 | 41-194 | Sentence | denotes | The proof-of-principle amplification of choice is a MDA reaction, which is a non-specific isothermal method of amplification performed around 30 °C [50]. |
T93 | 195-285 | Sentence | denotes | MDA is a method of whole genome amplification (WGA), as it amplifies all present DNA [52]. |
T94 | 286-356 | Sentence | denotes | It is commonly used when the initial amount of DNA sample is very low. |
T95 | 357-492 | Sentence | denotes | After the WGA is performed, a sequence specific amplification can be done since the quality the amplified DNA by MDA is very high [53]. |
T96 | 493-629 | Sentence | denotes | The amplification reaction is illustrated below in Figure 1 (the contour of the amplified sequence is highlighted in black for clarity). |
T97 | 630-846 | Sentence | denotes | Starting with a double stranded DNA (dsDNA) molecule, a denaturation step at 95 °C is required, giving the random hexamer-primers and the ϕ29 DNA polymerase access to the bases of single stranded DNA (ssDNA) strands. |
T98 | 847-916 | Sentence | denotes | The hexamers anneal themself to aleatory parts of the ssDNA sequence. |
T99 | 917-985 | Sentence | denotes | These hexamers work as initiation sites for the ϕ29 DNA polymerases. |
T100 | 986-1100 | Sentence | denotes | After denaturation at 95 °C, the mixture is cooled down to ice temperature and the rest of the reagents are added. |
T101 | 1101-1301 | Sentence | denotes | The mixture is heated up to ~30 °C so the polymerase starts to complete the complementary ssDNA sequence, creating again a dsDNA strand, eventually it encounters a hexamer from another annealing site. |
T102 | 1302-1439 | Sentence | denotes | Once this happens the polymerase will lift up that hexamer and starts to separate the amplified sequence formed from that annealing site. |
T103 | 1440-1537 | Sentence | denotes | As the polymerase displaces the formed strand ahead of it, it continues to complete the sequence. |
T104 | 1538-1757 | Sentence | denotes | The displaced strand becomes a new ssDNA strand and therefore, it gives new sites for more primers to attach and initiation sites for the polymerase, continuing the amplification, and thus creating a web of DNA strands. |
T105 | 1758-1844 | Sentence | denotes | Finally, the inactivation of the polymerase is done by heating up the system to 65 °C. |
T106 | 1845-2089 | Sentence | denotes | Even though MDA is considered an isothermal process, prior to the reaction and to the addition of most reactants, the dsDNA and a buffer are heated up to 95 °C to denature the dsDNA to ssDNA and to give hexamers the initial access to the ssDNA. |
T107 | 2090-2170 | Sentence | denotes | After the amplification reaction, the polymerase has to be inactivated at 65 °C. |
T108 | 2171-2314 | Sentence | denotes | However, this does not require fast temperature changes, as would be the case with, for example, the temperature cycling in PCR amplifications. |
T109 | 2315-2531 | Sentence | denotes | This, together with the robustness of the amplification (it is a self-limiting reaction that amplifies all present DNA [50]) makes MDA perfectly suitable as proof-of-principle amplification reaction for such devices. |
