immunoassayprodukter

Immunoassayprodukter are reagents, kits and related consumables designed to enable immunoassays, tests that detect and quantify analytes through antigen–antibody interactions. They form the core of many diagnostic and research workflows and include products for enzyme-linked, chemiluminescent, fluorescent, and lateral flow formats.

Common components are capture or detection antibodies, antigens or standards, enzyme or fluorescent labels, substrates, buffers, wash solutions, calibrators, controls, and solid supports such as microplates or membranes. Kits may be single-use or modular, allowing assembly of assays for specific targets. Major formats include ELISA kits, lateral flow immunoassays (rapid test strips), and automated immunoassays that use chemiluminescence or fluorescence detection.

Applications span clinical diagnostics (hormones, infectious agents, therapeutic drugs), veterinary testing, food and environmental safety, and basic research. Workflow typically involves sample preparation, incubation with antibodies or antigen-coated surfaces, washing, signal development, and detection. Signals are measured by enzyme activity, fluorescence, or chemiluminescence and quantified against a standard curve.

Quality and regulatory aspects are central to immunoassay products. Lot-specific quality control, performance validation (sensitivity, specificity, precision), and stability testing are common, with many products sold as regulated in vitro diagnostics in their respective markets. Storage and handling vary by component, but refrigerated or frozen storage is common, with some reagents provided lyophilized for reconstitution.
