ELISA Kits
Measure cytokines, hormones, growth factors and other biomarkers in serum, plasma, cell-culture supernatant and tissue lysates. Sandwich ELISA kits for proteins and competitive ELISA kits for hormones and small molecules — ready to use, with standards and a pre-coated strip-well plate.
From high-sensitivity cytokine kits to competitive hormone assays, pick the range built for your target.
Competitive kits for hormones, peptides and small molecules.
ELISA-format transcription factor activity assays.
Monitor therapeutic antibodies and biosimilars.
Measuring many analytes from one small sample? See multiplex ELISA, or compare immunoassay formats.
Captures the target between two antibodies, so signal rises with concentration. The most sensitive choice for proteins such as IL-6, TNF-alpha and other cytokines.
Suits targets too small to bind two antibodies, such as cortisol, dopamine and other hormones or small molecules. Here the signal falls as concentration rises.
Each product page states the format, detection range and sensitivity.
Ready-to-use kits with clear, streamlined protocols.
Quantify targets in serum, plasma, supernatant or lysate.
Consistent performance run after run.
Standards and strip-well plates included.

Start with your target and species, then check the kit is validated for your sample type and that its detection range covers the concentration you expect.
Prices are shown on each product page. Contact us for bulk pricing, or use our custom ELISA kit service if your target isn't listed.
Our complete ELISA guide covers every step of the protocol, and 101 ELISA troubleshooting tips helps with high background, weak signal or poor standard curves. Our PhD-level team can also help you pick a kit or troubleshoot a run.
An ELISA (enzyme-linked immunosorbent assay) kit contains everything needed to quantify a specific protein, hormone or small molecule in a sample: a pre-coated 96-well plate, standards, detection reagents, substrate and buffers.
A sandwich ELISA captures the target between two antibodies, so signal rises with concentration; it is the most sensitive choice for proteins such as cytokines. A competitive ELISA suits small targets like hormones, where signal falls as concentration rises.
Most kits are validated for serum, plasma, cell-culture supernatant and tissue lysates. Each product page lists the validated sample types and recommended dilutions.
Sensitivity varies by target and is stated on each product page. High-sensitivity cytokine kits reach around 1 pg/mL.
Typical lead time is 7–10 days. Our PhD-level team can confirm availability for a specific kit.
Yes. Contact us for bulk pricing on multi-kit studies, core facilities and distributors. If your target is not listed, our custom ELISA kit service can develop one.
ELISA is the standard choice for quantifying one target per well. To measure many analytes from a small sample, a multiplex assay may suit better; see our guide to immunoassay formats.
