TouchGene Gradient

A Techne Touchgene Gradient is a thermal cycler that uses a screen to control the temperature across its heating block, allowing researchers to optimize PCR reactions by running multiple temperature conditions simultaneously within a single experiment. It achieves this by creating a linear temperature gradient across the block, enabling users to find the optimal annealing temperature for their specific samples. The "Touchgene" aspect refers to its large, user-friendly touch-sensitive screen for programming and real-time monitoring of the experiment.
