Embodiment Construction

[0186] The synthesis of DNA molecules in channels can take place with use of standard synthons, for example phosphoramidite building blocks, with suitable protective groups, for example dimethoxytrityl (DMT). A corresponding fluidic DNA synthesis can take place starting from a linker coupled to the solid phase.

[0187] This format can be combined for the preferred embodiment of the invention with a light-dependent control of the DNA synthesis. For this purpose, protective groups which permit light-dependent deprotection are known, so that the protective group, which is usually linked on the 5' carbon atom of the synthon, is eliminated by light of suitable wavelength. The synthesis of nucleic acids with a length of 18 or more nucleotides is possible in capillaries in this way.

[0188] The reaction products can be analyzed, for example by high performance liquid chromatography (HPLC), by detaching the synthesized DNA oligomer, as is possible on use of suitable linkers. In this case it is ...

Abstract

A method for producing a support for determining analytes. The method comprises the steps of (a) providing a support comprising at least one channel, comprising a conduit having an intake and an outlet for passing fluid from the intake to the outlet, in the support body, (b) passing liquid with building blocks for synthesizing polymeric receptors through the channel or channels of the support body, (c) site- and/or time-specifically immobilizing the receptor building blocks in each case on predetermined positions in the channel or channels by illumination and (d) repeating steps (b) and (c) until the required receptors have been synthesized in each case on the predetermined positions.

Description

1 AREA OF APPLICATION OF THE INVENTION[0001] 1.1 Background[0002] The precise detection of biologically relevant molecules in defined investigation material is of outstanding importance for basic research in the biosciences and for medical diagnostics, and some other disciplines. In this connection, the genetic information is present in the form of an enormous variety of different nucleic acid sequences, the DNA. Realization of this information leads via the production of transcripts of the DNA in RNA usually to the synthesis of proteins, which in turn are frequently involved in biochemical reactions.[0003] The detection of particular nucleic acids and the determination of the sequence of the four bases in the chain of nucleotides, which is generally referred to as sequencing, provides valuable data for research and applied medicine. In medicine, it has been possible to a greatly increasing extent to develop, through in vitro diagnosis (IVD) instruments for determining important par...
