WebThe annealing gradient should range from the original annealing temperature to the extension temperature (two-step PCR). If high DMSO concentration is used, the annealing temperature determined by the guidelines above must be lowered, as DMSO decreases the melting point of the primers. WebThe geothermal gradient is defined as the increase in temperature with depth in the Earth. In normal continental crust a typical geothermal gradient within the first 3 to 5 kilometers (2 or 3 miles) of Earth’s surface is about 25°C/km. This gradient, however, is not sustained but decreases to no more than about 16°C/km at a depth of 40 km.
