摘要:
The invention relates to a method for the selection and identification of at least on representative (interaction partner) from a plurality of peptide or protein molecules, which can specifically interact with at least one representative from a plurality of target molecules, forming a bond. The inventive method comprises the following steps: (a) a virus system consisting of a plurality of viruses, wherein each virus respectively presents at least on representative from the plurality of peptide or protein molecules on the surface thereof, is brought into contact with the plurality of target molecules (ligands) which are immobilized on the surface of a solid phase carrier such that they are position addressable in a two-dimensional grade; (b) unbound viruses removed from the surface thereof; and (c) the interaction partner is identified by detection and determination of the position of the bond between the immobilized ligand and the interaction partner presented by the virus with the aid of a marker-free detection method. The described method makes it possible to concentrate viruses presenting interaction partners by means of an optionally cyclic repetition of selection. Optionally, selected interaction partners are recombinantly expressed after identification of the coding nucleotide sequence.

The invention relates to a sensor arrangement comprising a radiation-conducting substrate, said arrangement having a plurality of sensor fields and separating regions for separating the individual sensor fields from the respectively adjacent sensor fields. Said separating regions are formed by a separating agent layer that causes a reflectivity lower than 0.5 for radiation from the substrate on the interface between the separating agent layer and the substrate, at least in a first region adjacent to the interface between the separating agent layer and the substrate, and an extinction higher than 0.95 at least in a second region located above the first region, on the side opposing the substrate.

The invention relates to an SPR sensor array comprising a plurality of SPR sensor surface areas (120) arranged on a substrate (10, 20) in a two-dimensional matrix located in a plane to which the SPR sensor surface areas (120) are parallel and whereby radiation capable of exciting surface plasmons in the SPR sensor surface areas (120) under specific physical conditions can be guided through the substrate (10, 20) to be reflected from the SPR sensor surface areas, as well as separating means (110) for separating each SPR sensor surface area (120) from its neighboring SPR sensor surface area (120), wherein the separating means (110) and SPR sensor surface areas (120) are provided such that at least outside of surface plasmon resonance occurring in the SPR sensor surface areas (120) the radiation (40) guided through the substrate (10, 20) is reflected in the region of the separating means to a different degree than in the region of the SPR sensor surface areas (120) to create a contrast between the separating means (110) and the SPR sensor surface areas (120) at least outside of surface plasmon resonance occurring in the SPR sensor surface areas (120) in the radiation reflected by the SPR sensor surface areas (120) and the separating means (110).

The present invention relates to the use for affinity purification of an antibody or an fragment of an antibody, of a ligand-substituted matrix comprising a support material and at least one ligand covalently bonded to the support material, the ligand being represented by formula (I) wherein Sp is a spacer group; v is 0 or 1; Am is an amide group —NR1—C(O)—, and wherein either NR1 is attached to Ar1 and —C(O)— is attached to Ar2, or —C(O)— is attached to Ar1 and NR1 is attached to Ar2; and R1 is hydrogen or C1 to C4 alkyl, preferably hydrogen or methyl; and more preferably hydrogen; Ar1 is a divalent 5- or 6-membered substituted or unsubstituted aromatic ring; Ar2 is 5- or 6-membered heterocyclic aromatic ring which is (a) attached to a further 5- or 6-membered aromatic ring via a single bond; or (b) fused to a further 5- or 6-membered aromatic ring as part of a multicyclic ring system; or (c) attached to at least one substituent selected from C1 to C4 alkyl; C2 to C4 alkenyl; C2 to C4 alkynyl; a halogen; C1 to C4 haloalkyl; hydroxyl-substituted C1 to C4 alkyl; C1 to C4 alkoxy; hydroxyl-substituted C1 to C4 alkoxy; C1 to C4 alkylamino; C1 to C4 alkylthio; and combinations thereof.
