Immunoassay Kits

Immunoassay kits are essential tools for detecting and quantifying biomolecules such as proteins, peptides, hormones, antibodies, and cytokines using antigen–antibody interactions. This subcategory includes ELISA kits, lateral flow assays, chemiluminescent immunoassays (CLIA), and multiplex bead-based assays designed for high sensitivity and specificity across a range of biological samples. These kits are widely used in immunology, infectious disease research, oncology, endocrinology, and clinical diagnostics. Common applications include biomarker validation, drug screening, vaccine response monitoring, and therapeutic protein quantification. Researchers use immunoassay kits to evaluate immune responses, detect disease biomarkers, and assess sample quality during bioprocessing and QC. Each kit typically includes pre-coated microplates or membranes, capture and detection antibodies, substrates (e.g., TMB or luminol), wash and dilution buffers, and a detailed protocol optimized for reproducibility and scalability. Wasteless Bio offers a curated selection of unopened, surplus immunoassay kits from academic labs and biotech manufacturers. Whether you're running a single-analyte ELISA or a multiplex cytokine panel, each listing includes key specifications such as detection range, target species, assay format, and validated applications—making it easy to integrate high-quality kits into your workflow without overspending. By sourcing these kits through Wasteless Bio, laboratories can reduce operational costs and avoid disposal of perfectly functional assay components, supporting a more sustainable and efficient procurement model across the life sciences.
