  • immunocap isac is a highly advanced tool for revealing the patients ige antibody profile. it is the result of a combination of innovative biochip technology with cutting edge research in molecular allergology. immunocap isac is the only in vitro diagnostic test for simultaneous measurement of specific ige antibodies to a broad spectrum of allergen components.

    Highly advanced technology answering the clinical questions

    Based on modern biochip technology, ImmunoCAP ISAC is a miniaturized immunoassay platform where allergen components are immobilized in a microarray.

    This advanced technology enables a simultaneous measurement of ige antibodies to a fixed panel of 112 components from 51 allergen sources in a single step, using only 30 ul of serum or plasma.

    Both capillary and venous blood sampling can be used, where capillary blood sampling enables a less invasive procedure e.g. for testing young children.

    ImmunoCAP isac is the first multiplex in vitro diagnostic tool for the allergy specialist that is based exclusively on allergen components.

  • the Future oF multiplex molecular allergologythe great power of microarray-based miniature solid-phase immunoassays lies in their potential to investigate in parallel large numbers of analytes in a variety of biological samples.

    immunocap isac allows clinical evaluation of many allergen components using only very low volumes of patient samples.

  • principles oF the test procedure

    the allergen components are spotted in triplets and covalently immobilized to a polymer coated slide. each slide contains 4 microarrays giving results for 4 different samples per slide.

    ImmunoCAP ISAC is a two-step assay:

    1. ige antibodies from the patient sample bind to the immobilized allergen components.

    2. allergen-bound ige antibodies are detected by a fluorescence- labeled anti-ige antibody.

    The test procedure (including washing and incubation steps) gives a total assay time of less than 4 hours.

    Fluorescence is measured with a laser scanner and results are evaluated using Phadia Microarray Image Analysis (MIA) software. the mia sW has a user-friendly interface and enables automatic readout and customized result reports.

    immunocap isac is a semi-quantitative test and results are reported in ISAC Standardized Units (ISU) giving indications of specific IgE antibody levels.

  • technical Features Frontline biochip technology a highly advanced in vitro

    diagnostic test using multiplexing technology for allergen specific ige antibody measurements.

    Only allergen components high-quality recombinant and purified allergen components are used.

    Efficient profiling tool enables measurement of IgE antibodies to a fixed panel of the 112 most relevant allergen components from 51 sources in a single test.

    Small sample volume only 30 l of serum or plasma.

    Flexible sample taking both serum and plasma (heparin) samples from capillary and venous blood can be used.

    Semi-quantitative determination based on fluorescence measurements, results are reported within a measuring range of 0.3 100 ISU-E (ISAC Standardized Units) giving indications of ige antibody levels. the isu-e are standardized to immunocap specific ige units.

    Performance: sensitivity varies from 0.3 1.0 ISU-E depending on the allergen component, no interference even from very high total IgE.

    CV% is < 25 for values > 1 ISU.

    Structured result report a user-friendly software generates structured result reports including guiding comments for faster interpretation.

    immunocap isac contains a wide array of proteins from various allergen sources.
