ELISA kits and immunoassays
Save time with consistent, sensitive, and specific immunoassay tools.
Our comprehensive immunoassay portfolio offers precision tools designed to accelerate your biomarker research. From ELISA kits to antibody pairs find the solution you need for your project.
SimpleStep® ELISA
- Single-wash, easy protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity, and reproducibility from superior antibodies
Sandwich ELISA
- Single-wash protocol cuts assay time to under 90 minutes. High sensitivity, specificity, and reproducibility from superior antibodies.
Sandwich ELISA kits
The most widely used type of ELISA utilizes two antibodies to detect an antigen with high specificity. One antibody binds to the antigen, and the other detects it, making it ideal for sensitive protein quantification. Our range of over 3,000 sandwich ELISAs for measuring over 2,000 analytes in 20+ species delivers high-performance, ready-to-use solutions for accurate and reproducible protein quantification
Competitive ELISA kits
Competitive ELISAs measure antigen levels by detecting how much it interferes with binding, producing an inverse signal. Our competitive ELISA kits are expertly designed for the sensitive and specific detection of small molecules, ideal for quantifying hormones, metabolites, and signaling compounds with confidence and ease.
SimpleStep ELISA®
With a single-wash 90-minute protocol and recombinant antibodies for superior specificity, these kits simplify traditional ELISA workflows without compromising sensitivity or reproducibility. Ideal for researchers seeking speed and accuracy, SimpleStep ELISA kits accelerate data generation across a wide range of targets and sample types.
ELISA kits are essential tools for quantifying proteins, peptides, hormones, and other biomolecules in complex biological samples. Widely used in immunology, oncology, neuroscience, and clinical research, ELISA enables scientists to measure analyte concentrations with high specificity and sensitivity.
Our ELISA kits span both sandwich and competitive formats, and are designed to streamline workflows and deliver reproducible, publication-ready data. Each kit includes pre-optimized reagents and detailed protocols, minimizing setup time and ensuring consistent performance across experiments.
Our proprietary SimpleStep ELISA® technology further simplifies the process with a one-wash protocol and recombinant monoclonal antibodies, reducing assay time to just 90 minutes without compromising accuracy. Our kits offer broad species coverage, validated sample compatibility, and rigorous quality control.
