MJ Research PTC-200 DNA Engine is an easy-to-use, reliable and compact thermal cycler. It features interchangeable sample blocks (the Alpha unit family) which can accommodate many kinds of tubes, micro-plates, and slides. Its dimensions are 24 x 35 x 17cm. MJ Research PTC-200 is equipped with hot Bonnet heated lid for oil-free cycling. It has inbuilt intuitive software with easy-to-read user interface for quick programming, editing, file management, and password protection. It gives you a choice of calculated sample temperature control for highest accuracy and speed.
MJ Research PTC-200 features space-saving design for quick setup and easy transportation. It offers instant incubate feature for continuous-temperature incubations. MJ Research PTC-200 DNA Engine provides networking for up to 15 machines which enables convenient remote operation and documentation of runs. It can save 200 typical programs in up to 12 individual folders.
MJ Research PTC-200 comes with a one DNA Engine base, one Alpha, two spare fuses, one power cord, one probe (if purchased), PTC-200 DNA Engine Operations Manual, product registration card (for US customers only), extended warranty application ( for US customers only), and DNA Engine Driver remote software request form. PTC-200 DNA Engine requires 100–240VAC, 50–60Hz, and a grounded outlet. It requires a constant supply of air that is 31˚C or cooler to remove heat from the Alpha unit’s heat sink. Air is taken in from the vents at the front, back, and bottom of the machine and exhausted from vents on both sides. To avoid overheating, performance problems, software error messages, and sudden shut downs of the machine, ensure that the air supply is adequate and air flow is unobstructed.

- Rapid ramp rates of up to 3.0°C/sec
- Two thermal control options: block control or calculated control
- Choice of two heated-lid designs that accommodate many vessel types and various sealing options, allowing maximum flexibility in experimental designs—heated lid temperatures can be set with any DNA Engine instrument
- Manual Hot Bonnet® heated lid with a unique thumbwheel for adjusting height and pressure
- Moto Alpha™ units can be remotely commanded to open, close, and adjust height and pressure—alternatively, they may be opened and closed with the touch of a button for highly repeatable sealing

Temperature gradient available on all DNA Engine family thermal cyclers
The MJ gradient feature is now standard on any new cycler within the DNA Engine family equipped with the 96-well Alpha unit, including the original DNA Engine cycler, the DNA Engine Tetrad® 2cycler, the DNA Engine Dyad® cycler, and the Dyad Disciple™ cycler.
Molecular biology labs routinely need to optimize incubation temperatures for thermal cycling reactions. Optimization is critical but not always easy to do. Even after calculating the Tm (melting temperature) of a primer, the annealing temperature often needs to be determined empirically, which involves repeating a reaction at many different temperatures. Similar time-consuming tests may also be used to optimize the denaturation temperature.
The MJ gradient feature allows you to perform optimization reactions in a single experiment by using a range of temperatures simultaneously. With the thermal gradient software, you can program a temperature gradient up to 24°C across a 96-well sample block. The gradient feature also works with calculated sample temperature mode, so you can generate fully optimized programs in a single step.
Advanced features make optimization easy.
Dynamic ramping means that the temperature gradient forms during ramping. All wells come to the designated temperature at the same time, making the incubation period consistent among all samples in the experiment.
This graph represents the superposition of thermal measurements taken from twelve columns in four different cyclers (there are actually 48 separate traces in the graph). Four cyclers were programmed to develop a 45-65°C gradient—the bottom traces represent the leftmost columns and the top traces the rightmost columns. This was done to demonstrate both the extraordinary thermal performance of the instruments, and the cycler-to-cycler reproducibility of the profiles. Note too the even spread of temperatures, which allows for the greatest quantity of useful data.
The twelve points across the graph represent the temperature values displayed for each column of the block, with the size of the point far smaller than the specified error (±0.4°C). Four traces from four cyclers have been superposed, showing the cycler-to-cycler consistency.
Methods: Both graphs incorporate data from 48 wells of each cycler, taken with NIST-traceable, laser-trimmed thermistors.
Since 1994, the DNA Engine family of thermal cyclers has used multiple zones of thermal control across its sample blocks to deliver remarkable well-to-well temperature uniformity. Sophisticated algorithms use readings from three sensors in the block to adjust up to four separately-controlled heating/cooling elements, quickly and effectively bringing the sample block to uniformity. This same technology is used to establish a highly reproducible temperature gradient across the sample block using software alone – unlike other gradient-enabled thermal cyclers, which require specialized hardware. The MJ gradient software is now a standard feature, offered at no extra cost, on all new DNA Engine, Tetrad™ 2, Dyad™, and Dyad Disciple™ cyclers, and the DNA Engine Opticon® continuous fluorescence detection system.
