PCR Gradient Thermocycler (ABI)
Description
A PCR (Polymerase Chain Reaction) gradient thermocycler is a specialized instrument designed for amplifying DNA sequences. It allows for simultaneous testing of multiple annealing temperatures, optimizing PCR conditions for various samples.
Features of a Good PCR Gradient Thermocycler
1. Gradient Capability
– Ability to set a temperature gradient across a block (e.g., 4°C to 100°C) to optimize annealing conditions.
2. Accuracy and Precision
– High precision in temperature control, typically ±0.5°C to ensure reproducibility.
3. Multiple Sample Capacity
– Configurations to accommodate various plate formats (e.g., 96-well, 384-well).
4. User-Friendly Interface
– Intuitive touchscreen or software for easy programming and tracking.
5. Fast Heating and Cooling
– Quick thermocycling to reduce overall run times, with ramp rates generally around 3°C to 5°C per second.
6. Data Logging
– Options for storing protocols and reviewing temperature profiles post-experiment.
7.Flexible Programming Options
– Supports various PCR protocols, including steps for denaturation, annealing, and extension.
