GRADIENT

The gradient feature of the Prime Elite Satellite can be useful in optimising the annealing conditions for

primers. A gradient can be set around a temperature in any step of a program. The set temperature is

the temperature in the middle columns of the block and the gradient is the variation at the two

extremes of the block; the left hand columns being the coolest and the right hand columns the hottest.

The maximum gradient temperature range which can be set is 30ºC (96-well block) and the minimum

is 1ºC; the lowest temperature is 10ºC or 20ºC below ambient and the hottest temperature is 100ºC.

Examples of acceptable gradients for a 96-well block are given in the table below:
