摘要:
A receiving device for object holders comprises a base part. A plurality of centering elements are connected with the base part. The centering elements are arranged such that a plurality of receiving areas for receiving one object holder each are configured. The centering elements form a preferably circumferential centering frame around each receiving area.

An analyzing device for analyzing chemical and/or biological samples comprises a plurality of base parts, e. g. object holders, in a receiving device. The base parts are closed by a lid which is configured such that each base part and the lid form a test chamber for receiving the sample. Further, a conveying means for moving the sample in the test chamber is provided. The pumps of the conveying means are connected via channels with the test chamber and are controlled such that a portion of the sample liquid is alternately drawn off the test chamber and supplied back thereto by the pumps.

The invention relates to a support. Oligonucleotides or polynucleotides are covalently bound with the 5′- or 3′-termination on least one main surface of said support via bifunctional spacers and bifunctional linkers. The support is characterized in that the oligonucleotides or polynucleotides which are covalently bound with the 5′- or 3′-termination via bifunctional spacers and bifunctional linkers comprise 200 to 600 bp, and the oligonucleotides or polynucleotides can be obtained by using a method which comprises the following steps: Selecting homologous regions of mRNA of a target species and of at least one model species; selecting amplification primers which permit the amplification of 200 to 600, preferably 200 to 400 bp long nucleic acids from the homologous regions of both the mRNA of the target species and the mRNA of at least one model species, whereby the amplification primers optionally comprise a maximum of 1 mismatch per 6 nucleic acids of the amplification primer; immobilizing the nucleic acids on at the least one main surface of the support, said nucleic acids being obtained from the corresponding 200 to 600 bp long nucleic acids which are amplified for the target species or for the at least one model species by amplifications using the amplification primers.

The invention relates to a cell containing a gene encoding a conditional transgenic surface marker that is detectable upon expression on the surface of the cell, wherein the gene encoding a conditional transgenic surface marker comprises: (i) a promoter, operably linked to (ii) a first transcription sequence, and (iii) a second transcription sequence encoding the surface marker, whereby the first transcription sequence prevents the transcription of the second transcription sequence, whereby the first transcription sequence is conditionally removable such that the second transcription sequence is transcribable, and whereby the surface marker renders the cell sortable through the detection of the conditional transgenic surface marker. Furthermore, the invention relates to a construct for generating such a cell, and to a method for separating such a cell from a population of cells.

摘要:
A device for carrying out chemical and/or biological reactions comprises a sample chamber (38) formed by a first portion (12) and a second portion (26) and designed for holding the sample. With the aid of a moving means (46,50) the sample can be moved in the sample chamber (38). The second portion (26) is connected via an intermediate element (27) with a heating and cooling-control element (29) for heating and cooling the sample. For ensuring good temperature conductivity and resistance to the sample of the second portion (26), in a preferred embodiment, the second portion (26) is made of ceramic.
摘要:
A nucleic acid complex with an anchor oligonucleotide, an arbitrary nucleic acid or an arbitrary oligonucleotide and a linker nucleic acid, wherein the linker nucleic acid is partially hybridized with the anchor nucleotide and partially hybridized with the arbitrary nucleic acid or the arbitrary oligonucleotide and the anchor nucleotide is immobilized on a support by its 3′-terminus.
