Definitions
- the invention relates to a method and an apparatus for the mask-free production of biopolymers, which are synthesized, for example on a slide, by an exposure sequence.
- the fields are used to detect the presence of complementary nucleic acids in a liquid sample.
- the regionally addressable irradiation of predefined regions on the surface allows the immobilization of oligonucleotides and other biopolymers in the activated regions of the
- the surface of the substrate body is irradiated through a mask with a light source which emits a wavelength in the range between 280 and 420 nm, it being possible to select only certain preselectable regions for irradiation with each individual mask.
- US 5,744,305 relates to materials applied in the form of a field to a carrier. These serve a synthesis strategy for the production of chemically divergent substrates. Photoactive protective groups of molecules are used to achieve chemical synthesis processes that run in parallel in areas controlled by light.
- Binary masking techniques are used in the context of an exemplary embodiment. In the disclosed method, various chemical components are synthesized in parallel using a masked radiation source or using an activator. The lighting pattern determines which areas of the slide are prepared for a chemical reaction. The masking technique is also used here to select different areas to be exposed on the slide.
- US 5,143,854 relates to a method for the photolithographic synthesis of polypeptides and a search method.
- polypeptide fields are synthesized on a substrate by applying photoactive groups to the surface of a substrate which expose certain regions of the substrate to the light in order to activate the regions.
- An amino acid monomer with a photoactive group is applied to the regions activated in this way, the activation and attachment steps being repeated until polypeptides of the desired length and sequence are synthesized.
- the resulting field can be used to select those peptides that are able to bind a receptor.
- 5,143,854 proposes using a diode light source for exposure and exposing the substrate to be exposed in accordance with the partial areas to be exposed. This procedure requires a complex mechanical control mechanism in order to align the substrate exactly in accordance with the areas to be exposed by the light-emitting diode. This mechanical alignment must be carried out each time anew for each new field to be exposed.
- the control mechanism places very high demands on the manufacturing accuracy in order to achieve the above-mentioned positioning positions.
- micromirrors In addition to masking the biopolymer regions to be exposed on the slide, it is known from WO 99/42813 to expose DNA sequences or polypeptides or the like by means of a device with controllable micromirrors, the micromirrors forming a coherent field which is composed of electronically addressable individual micromirrors is. A common light source is assigned to this.
- the biopolymers on the slide are activated in certain patterns, the sequentially offered monomeric building blocks being coupled to the controlled areas. This process continues until all elements of a two-dimensional field on the substrate have reacted with the desired monomer.
- the micromirror field can e.g. can be controlled in connection with a DNA synthesizer in such a way that the image sequence through the micromirror field is coordinated with the liquid sample applied to the slide.
- photoactive monomeric building blocks or photoactive surfaces are used to create a site-oriented Enable synthesis.
- the action of light serves to remove the photoactive groups of the monomeric building blocks or surfaces, so that a synthesis or an immobilization step can then take place at these points of the action of light.
- masks are used or micromirror fields are controlled.
- n-nucleotides from an ensemble of four different bases are linked in an n-mer sequence
- 4 x n masks are required.
- 20 x n masks are required.
- Such a mask set must not only be provided in advance, but must also be adjusted very precisely during the exposure. This is accompanied by a considerable technical outlay, so that the masking process is not worthwhile for small series, but a new mask set has to be provided for each new synthesis.
- the invention has for its object to provide a method for the synthesis of biopolymers, which simplifies exposure and activation of individual areas of a biopolymer-containing slide and makes it mask-free. According to the invention, this object is achieved by the features of claims 1 and 15.
- Biopolymers such as Synthesize oligonucleotides and peptides, for example. Furthermore, biopolymers can be immobilized in a light-controlled manner; no masks are needed, the preparation and preparation of which are used
- nucleotides and peptides can be synthesized on surfaces.
- biopolymers can also be immobilized on the surfaces. Biopolymers are understood to mean, for example, nucleic acids, their analogs (e.g. PNA, LNA), amino acids, peptides, proteins, carbohydrates, and combinations of these.
- the switching on and off of the light-emitting diodes of the light-emitting diode array from 9, 16, 25 or up to 100 or even more light-emitting diodes is preferably controlled automatically by a computing unit.
- the computing unit contains the radiation arrangements desired in each case in a stored form.
- the exposure time during which the individual light-emitting diodes selected areas of a slide can also be entered via the computing unit irradiate.
- Such light-emitting diodes are preferably used which emit high-energy radiation in the UV range.
- exposure processes can be carried out simultaneously by the light-emitting diode array containing several light-emitting diodes. A sequential sequence of exposure processes can also be set up.
- the simultaneity of the activation of a plurality of light-emitting diodes of the light-emitting diode array can be achieved, for example, by the activation of the light-emitting diodes via the parallel interface of a computer.
- the parallel execution of exposure cycles taking into account the sequence of individual exposure times stored in the computing unit, considerably shortens the synthesis of biopolymers.
- the substrate for the biopolymers to be synthesized thereon is located in a feed device below a translucent area.
- the feed device can be configured, for example, as a flow chamber in which the chemicals required for the synthesis to be carried out can be offered sequentially.
- the respective sequences for the individual fields of the array to be synthesized are first entered into the controlling computer. With a corresponding program, the computer controls the individual light-emitting diodes in the light-emitting diode array correlated to sequential and cyclical supply of the individual monomers in accordance with these specifications.
- the exposure preferably takes place spatially separate from the chemical synthesis in order to exclude any external disturbing influences during the exposure.
- the sequential sequence of immobilization sites for freely selectable biopolymers can also be stored in the computing unit.
- the device proposed according to the invention By means of the device proposed according to the invention, parallel, light-controlled synthesis or immobilization of biopolymers can be achieved by computer-assisted parallel control of individual light-emitting diodes without the need for masks.
- the light-emitting diodes are preferably designed as light-emitting diodes which emit light in the UV wavelength range.
- the light-emitting diode array can be optically imaged on the desired scale. Appropriate optical devices are used for this.

- FIG. 2 shows a fluorescence image of an oligonucleotide array, synthesized using a 4 ⁇ 4 light-emitting diode array after hybridization
- Fig. 3 four surface fluorescence images in four different
- Fig. 4 shows the structure of a sequence on a chip surface using a
- FIG. 1 shows the top view of a field with, for example, 4 x 4 individually controllable light-emitting diodes and the associated control electronics.
- FIG. 1 shows a light-emitting diode array 1, which is located below a slide 12 or below a chip surface 19.
- the arrangement shown in FIG. 1 is a light-emitting diode arrangement 1, which contains 16 individually electrically controllable light-emitting diodes 2; of the light emitting diodes 2 shown, the light emitting diodes A 1? B 3 and D 4 are shown in more detail, which are to be controlled for example for one of sixteen DNA sequences.
- Each activation of a light-emitting diode 2 of the light-emitting diode array 1 takes place via separate control lines 4, the individual light-emitting diodes 2 being connected to the supply part 8. Furthermore, the individual light-emitting diodes 2 of the light-emitting diode array 1 are each connected to resistors 5, from which further lines extend to memory cells 6 and 7, respectively.
- the memory cells 6 and 7, in turn, are controlled via a parallel interface 10 provided on a computing unit 22.
- the DNA sequences 20 and the exposure times required to remove the individual photolabile protective groups or the sequential sequence of immobilization sites can be stored in various files.
- the computing unit 22 can provide those chemicals required for the synthesis of biopolymers such as, for example, oligonucleotides or peptides, which, depending on the sequence to be treated, react at precisely predefined exposure locations after the unstable photo protection groups have been removed there. Due to the correlation of the sequences, with the inflow of chemicals and the associated exposure locations, a simultaneous exposure of several exposure locations can take place by using the parallel port 10 on the computing unit 22.
- biopolymers such as, for example, oligonucleotides or peptides
- photolabile protective groups In order to define, within a synthesis cycle taking place in a flow chamber, at which position which of the four nucleotide building blocks - deoxyadenosine, deoxythymidine, deoxyguanosine and deoxycytidine - is to be condensed, photolabile protective groups must be removed on the substrate support at predetermined times. The removal of the photolabile protective groups is necessary because only after their removal can a synthesis and the construction of a DNA oligomer be achieved.
- individual light-emitting diodes 2 of the light-emitting diode arrangement 1 are preferably designed as individually electrically controllable light-emitting diodes 2. These emit very high-energy radiation, preferably in the ultraviolet range with a wavelength of preferably 360 nm. However, light-emitting diode arrangements 1 can also be used, in which individual light-emitting diodes 2 are received, which emit radiation of a different wavelength, which is different from the UV range. The optimal wavelength of the light-emitting diodes 2 must be matched to the photochemistry used.
- the individual light-emitting diodes 2 of the light-emitting diode arrangement 1 it is determined at which point on the substrate support photo-protection groups are split off in order to enable the attachment of nucleotide building blocks to be coupled.
- three light-emitting diodes 2 are identified by way of example in FIG. 1, which are denoted by Aj, B 3 and D.
- the emitted high-energy radiation from the light-emitting diodes 2, denoted Ai, B 3 and D 4 preferably strikes the locations of the substrate carrier of the feed device and causes the unstable photo-protection groups to be removed at the precisely defined locations.
- the exposure time can be different, also depending on the sequence to be generated.
- the different exposure times that are to be observed by the light-emitting diodes with regard to their on time can also be stored in a file of the computing unit 22 and can thus be incorporated into the proposed exposure method.
- the protective groups are now removed at these positions on the substrate carrier, so that a chain extension can be achieved only at these well-defined locations on the substrate carrier within this synthesis step.
- the photolabile protective groups on the substrate can be split off, for example on the Positions 4 , B 2 and Dj take place, so that after the expiry of the exposure time required to remove the protective groups, a chain extension can only take place at these locations on the substrate with the provision of a monomeric unit to be guided through the flow chamber.
- the light-emitting diode arrangement 1 is used as an array of individual light sources without an individual mask set being required for each substrate carrier or each chip surface 19.
- preselection of the exposure locations, depending on the sequence file stored in the computer 22, small series can also advantageously be synthesized.
- the light-emitting diode arrangement 1 controlled by means of the computing unit 22 assumes both the function of the exposure and that of masking the area to be exposed, as a result of which the need to reposition masks can be completely eliminated. Inaccuracies in mask repositioning during the synthesis process using the mask process have in the past led to considerable quality deficiencies in biopolymer components synthesized in this way.
- a synthesized oligonucleotide array synthesized using an array of 4 ⁇ 4 individually controllable light-emitting diodes 2.
- this can also have any number, for example 25, 400 or up to several thousand individual ones Contain radiation sources in the form of light-emitting diodes, it being possible to decide whether they can be arranged square, rectangular, ring-shaped or also circular. That in Fig. 2 the array shown is a fluorescence image obtained by hybridization with a fluorescence masked complementary strand probe.
- FIG. 3 shows an overview of four surface fluorescence images, each with four different sensitivity levels.
- a 3 x 3 light-emitting diode array 1 was used to determine a sufficient exposure time.
- the four images show the same array, recorded in four different sensitivity levels of the detecting scanner.
- FIGS. 4.1 and 4.2 show the structure of a sequence on a surface 19 with a light-emitting diode arrangement 1 containing 4 individual light-emitting diodes 2.
