Definitions
- the invention relates to a device in the preamble of claim 1 Art.
- Devices of this type are used to carry out chemical reactions in reaction samples, that require different temperature levels one after the other, which are carried out in successively repeated cycles.
- PCR polymerase Chain Reaction
- Devices of this type are used to carry out the PCR (polymerase Chain Reaction) with which DNA sections are amplified for example with three successive temperature levels, namely the denaturation level, the annealing level and the elongation level.
- Hang there the reaction results such as Yield and selectivity from the reaction parameters such as. Temperature, time etc., which is optimized in experiments Need to become.
- Such devices can be used to examine individual reaction samples the reaction parameters of the PCR are still unknown and should be determined. In particular, they can also be used for simultaneous treatment a larger number of reaction samples can be provided, but for what the reaction parameters must be optimized in preliminary tests beforehand.
- stage temperatures can be extremely critical.
- To be able to determine temperature in a time-saving manner is a generic device known from DE 196 46 155 C2, in which the samples in one pass on one or more levels with different temperatures in the range the step temperature can be treated. With subsequent evaluation which is for the different temperatures within a temperature level Resulting reaction results can be the optimal step temperature be determined. With such devices, only one pass is required for this.
- the object of the present invention is a device of Generic type to create an improved optimization of step times allows.
- the device treats the samples in one pass different groups, each with one or more reaction samples belong, with different step times and thus enables the determination the optimal step time of one or possibly several temperature steps. It it has been found that the step time is also an essential reaction parameter at certain step temperatures can be, to a considerable extent the reaction results are affected. In contrast to the aforementioned known Construction that changes the cycle times of all samples equally and for optimization If the step time requires several runs, the optimal step time can be with the invention in a single pass, so much more efficient with regard to laboratory time and sample consumption.
- the device can of course also by setting the same step times for everyone Groups used on a pre-determined optimal step time for mass processing become. The step times can be changed for only one step or at all levels.
- the result is different cycle times between the groups of samples, so that at multiple cycle repetition in one pass the samples of different Groups are increasingly asynchronous.
- This can There are disadvantages, particularly with regard to the very large ones that then occur Temperature differences between the groups.
- The are therefore advantageous Features of claim 2 provided.
- This can be used to change the step time in one step by changing the step time in another Level are compensated so that the cycle time remains constant, so all Samples from the different groups run in a synchronous cycle. temperature deviations between the groups then appear only briefly and in particular in all cycles again and again at the same time, so that the Set the duration of the run constant conditions. This will make the Results can be clearly evaluated.
- the other to be varied in the dwell time Level is preferably a level that has no significant time dependency.
- the features of claim 6 are advantageously provided. They are in columns (or rows) arranged samples each provided on a temperature control device, which creates a temperature gradient across the gaps.
- the Columns are thermally insulated from each other and are different Times.
- Such a device is characterized by large technical Simplicity and can essentially be known from the prior art Make use of construction principles.
- the device according to the invention can advantageously with individual heating samples thermally insulated from one another. Then leave the group assignments of the samples are arbitrary.
- the samples one Groups do not have to be arranged side by side. Also larger temperature differences between neighboring samples can be easily to adjust.
- FIG. 1 shows a temperature control device according to the invention with a total of 24 Prohen 1, which are indicated as circles. It can be liquid filled wells in the device or in corresponding Wells of the device are thermally conductive receptacles that contain the reaction samples contain. The samples are in four columns and six rows in one rectangular grid arranged. The device is divided into four columns Groups in the form of blocks 2 divided against each other with insulating layers 3 are thermally insulated. The groups can also be different from columns be arranged, for example in rectangular, several reaction samples each contained blocks or the like. Also the number of reaction samples a wide range can be varied per row and column.
- heating devices 4 and 5 are arranged in thermally conductive contact, which generate a temperature gradient G T in each of the blocks 2 made of thermally conductive material, which in addition to the illustration as an arrow and with temperature information for the individual lines of reaction samples 1 is shown.
- the heating devices 4, 5 are from the temperature control device in a manner not shown in terms of time and the temperatures to be set controlled that the samples go through a cycle which in one example is shown in FIG 2 is shown.
- all the heating devices 4, 5 are controlled in such a way that all the samples with the same temperature on a ramp 6 up to denaturation level 7 heated at about 90 ° and held at this for a few seconds. thereupon by controlling the heating devices 4, 5 accordingly a ramp 8 cooled down to the annealing stage 9 at about 55 °, which in turn is held for a few seconds. Then it goes up via a ramp 10 the elongation level 11 of 70 °, which is held for some time. Then follows ramp 6 again and the cycle is repeated.
- the samples as shown in Figures 1 and 2, in four groups on the Annealing level for different times of one second, two seconds, held for three seconds.
- the four blocks 2 for held different times at the temperature of the annealing stage by appropriate time control of the heating devices 4, 5.
- the residence time would be 1 for all reaction samples be the same at annealing level 9 and again e.g. at the denaturation level 7 the time difference can be compensated.
- the temperature gradient G T shown in FIG. 1 is used for this purpose, which is applied in addition to the applied time gradient G t , in the case shown at the annealing stage 9. This is also shown in dashed lines in FIG. It can be seen that (dashed lines) six different temperatures are possible for the annealing stage 9, as they result from the temperature gradient in FIG. 1 in the six lines. As FIG. 2 also shows, all combinations of different residence times and different temperatures are possible.
- samples 1 can also be used, for example Individual heating and mutual thermal insulation. she can then be tempered differently in any arrangement and with different Residence times are operated.
- stage temperatures shown in Figure 2 are only given as examples. Depending on the reaction, the stage temperatures can can be chosen very differently. Also the step times shown in the range of a few seconds, depending on a very wide range if necessary, are changed.
