Choose the right ELISA kit
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.
Choose the right ELISA kit by considering what’s needed for your research. Every laboratory workflow is different, so we offer distinct kit formats to match your requirements:
- Sandwich ELISA kits: Best suited to capturing and detecting low-abundance analytes in complex samples. Designed to streamline workflows and deliver reproducible, publication-ready data.
- Competitive ELISA kits: This format is preferred when high specificity is required for low molecular weight targets. Minimizes setup time and ensures consistent performance across experiments.
- SimpleStep ELISA kits: These single-wash kit formats deliver optimized performance and highly reliable data in much less time, reducing assay time to just 90 minutes without compromising accuracy.
- Uncoated ELISA kits: A smart, cost-effective choice for high-volume screening, these highly adaptable kits offer flexibility and customization in situations where you need complete control of your assay environment.
SimpleStep® ELISA
- Single‑wash, easy protocol delivers results in under 90 minutes or as little as 55 minutes, depending on assay format
- High sensitivity, specificity, and reproducibility from superior antibodies
Sandwich ELISA
- Sensitive, specific analyte detection and quantification using a pair of antibodies
- Reliable protein measurement across complex samples with robust, reproducible performance
Competitive ELISAs
- Competitive ELISAs quantify antigen by measuring interference with binding, producing an inverse signal
- Sensitive, specific detection of small molecules, ideal for hormones, metabolites, and signaling compounds
Types of ELISA kit
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.
Matched antibody pair kits
Our matched antibody pair kits are designed to give researchers the flexibility of a DIY ELISA. Each kit includes a titrated capture and biotinylated detector antibody pair and a calibrated protein suitable for sandwich ELISA. By supplying the core antibody and protein components rather than a pre-coated plate, these kits let you adapt the assay conditions to different sample types and give you the flexibility to run your experiment as you want.
