ELISA

ELISA (Enzyme-Linked Immunosorbent Assay) kits and reagents are essential tools for the quantitative detection of proteins, peptides, hormones, antibodies, and cytokines. This category includes pre-coated plates, capture and detection antibodies, enzyme conjugates, substrates (e.g., TMB), and wash/binding buffers. Used extensively in immunology, clinical diagnostics, vaccine development, and biomarker validation, ELISA workflows allow researchers to perform sensitive and high-throughput protein quantification in biological fluids such as serum, plasma, and cell culture supernatants. Subtypes include sandwich ELISA, competitive ELISA, and direct/indirect formats, enabling versatile applications from disease diagnostics to drug efficacy monitoring. Wasteless Bio provides access to unopened, surplus ELISA kits and components from research institutions and biotech labs. Each product listing includes target analyte, assay range, sensitivity, and species reactivitysupporting reliable integration into new or ongoing studies while minimizing reagent waste.
