Sandwich ELISA kits

Find the kit you need in our extensive range of sandwich ELISA kits for accurate and reproducible protein quantification.

Cytokine ELISA kits

Cytokine ELISA kits offer sensitive and specific quantification of key immune signaling proteins, enabling the precise monitoring of inflammation, immune responses, and disease progression.

Species-specific ELISA kits

Species-specific ELISA kits ensure detection of target proteins with optimized sensitivity and minimal cross-reactivity. We offer sandwich ELISA kits to more than 20 different species.

Sandwich ELISA to support drug discovery

Sandwich ELISA assays support drug discovery by enabling precise quantification of target biomarkers, such as toxicity indicators and therapeutic proteins, across preclinical and clinical samples, facilitating efficacy assessment, safety profiling, and regulatory validation.

Sandwich ELISA kits are designed for the specific detection and quantification of an antigen between two layers of antibodies, hence the name 'sandwich'. The first layer, a capture antibody, is coated on the assay plate. Samples containing the target antigen are added, and any antigen present binds to this antibody. A detection antibody follows, forming a complex with the antigen. This antibody is linked to an enzyme or a detectable tag, and upon adding a substrate, a detectable signal is produced. The intensity of this signal is directly proportional to the amount of antigen in the sample.

Our sandwich ELISA kits are validated for high specificity and reproducibility across a wide range of samples. With easy-to-use protocols and multiple detection options, colorimetric, chemiluminescent, and fluorescent, they support a range of applications, from routine biomarker studies to complex disease research. Pre-optimized reagents help you get precise data faster, with less troubleshooting.
