Definitions
- the carrier is designed as a reflective solid carrier on which the binding protein is applied in a monomolecular, surface-active layer, and that after an incubation period, an immunoreaction between the antibody and the antigen caused increase in layer thickness of the protein-antibody layer is determined by an ellipsometric measurement method.
- the binding protein in a desired monomolecular surface-active layer.
- the monomolecular layer ensures that minimal substances can be used and detected.
- IgG immunoglobulin E antibodies
- IgE immunoglobulin E antibodies
- the antibody (IgG) - like a "Y" - consists of three areas. The Fab regions, corresponding to the poor, are responsible for the immune-specific responsiveness, while the Fc fragment, the foot end, reacts unspecifically.
- the IgG is coupled to the binding protein, for example protein A, via the Fc fragment.
- the carrier is scanned on a two-coordinate measuring table of an egg lipometer in a software-controlled manner by the laser beam of the egg lipometer. The result of the scanning process is then evaluated using an evaluation software.
- FIG. 2 shows a plan view of the carrier from FIG. 1 with a schematic illustration of a micropipette arranged in a row
- FIG. 3 a basic illustration, not to scale, of a side view of a carrier
- Figure 5 a simplified flow diagram of a method for the detection of antigen.
- a device for diagnosing allergic symptoms essentially consists of a sensor base 1 to which patient-specific allergens 2 can be connected.
- the carrier 3 is designed as a rectangular silicon plate on which a monomolecular layer of a binding protein 4 is arranged using the Langmuir-Blodgett technique (coating of monomolecular films of surface-active substances by means of a special dipping process).
- Protein A PrA
- protein G protein
- the binding protein 4 is arranged in a matrix in islands 8 on the Si plate.
- the carrier 3 has an exposed edge 6.
- the released edge 6 serves on the one hand as an attack surface for holders and, on the other hand, optionally as a reference surface for determining the refractive index of the carrier 3.
- the islands 8 are equipped with patient-specific antibodies 5. Different islands 8 have antibodies 5, each with a different specificity.
- Isotypic immunoglobulin G antibodies (IgG) separated from patient serum are used as antibody 5.
- immunoglobulin E antibodies IgE.
- the substance of the islands 8, on which an immune reaction has taken place is broken down into its atomic components.
- the separated elementary fractions achieved are reduced by the known binding protein and antibody proportions.
- the residual substance is the allergy-causing factor that is being sought and is evaluated in an allergen database or software library.
- This allergen database is a collection of all known allergens with the distribution of their elementary components, their biochemical structure as well as molecular structural elements and all conditions necessary for the evaluation.
- the separator result is reconstructed with the help of the allergen database using an integrated processing program and identified by comparisons and restrictions.
