WebIn this step, the PCR mixture is incubated at the extension temperature (generally 72°C) for a final 5–15 minute period. The duration of this final step also depends on the amplicon length and composition and should be optimized to ensure full-length polymerization and good yield of the target DNA ( Figure 8 ). WebSep 2, 2010 · HPLC was coupled on-line via a nanoelectrospray ion source (Proxeon Biosystems) to a LTQ-Orbitrap mass spectrometer (Thermo Fisher Scientific). Peptides were loaded onto the column with buffer A (0.5% acetic acid) with a flow rate of 500 nl/min, and eluted with 90 min linear gradient at a flow rate of 250 nl/min. Webgradient is the Gradient function, which greatly facilitates the optimization of PCR experiments. The gradient enables the temperature across the entire block to be varied within a range of up to 20 C; it can be programmed with every temperature step. .
