ELISA, CLIA and antibody pair formats for protein and peptide quantification

Our kit range spans ELISA, CLIA and matched antibody pairs for quantifying proteins, peptides and hormones in serum, plasma, cell lysate and tissue homogenate. Each kit ships with a validated protocol, standard curve reagents and a full datasheet, in a format built to match your throughput and sensitivity needs.

How it works

Plate-Based Immunoassay Formats

In a sandwich ELISA or CLIA kit, a capture antibody is pre-coated onto the plate, the sample is added, and a detection antibody binds the captured target. A colourimetric substrate (ELISA) or chemiluminescent substrate (CLIA) then generates a signal that is read against a standard curve to give a quantitative result. Antibody pairs supply the same matched capture and detection antibodies without a pre-coated plate, for labs setting their own plate, diluent and blocking conditions.

Category benefits

Why use our kits?

✓ Higher specificity from matched antibody pairs
Sandwich ELISA and CLIA kits use a capture and detection antibody matched to two non-overlapping epitopes on the same target, giving more specific binding than single-antibody formats.
✓ A faster route to a result
Our sandwich and competitive ELISA kits use fewer reagents and steps than our other ELISA formats, cutting down the opportunities for error mid-assay.
✓ CLIA sensitivity for trace and unknown concentrations
Chemiluminescent detection gives our CLIA kits greater sensitivity than chromogenic ELISA, useful when a target's concentration in the sample is not known beforehand.
✓ Coverage across targets, species and sample types
Our catalogue covers ELISA and CLIA kits for cytokines, cardiac biomarkers, metabolic hormones, neurological markers and oncology targets, across Human, Mouse, Rat, Bovine, Canine, Chicken and other species.

Kit Ranges

All three ranges quantify biomolecules in complex biological samples. The right choice depends on your analyte, the sensitivity you need and how much of the assay you want to run in-house. Choose a range below to browse that part of the catalogue.

Colourimetric ELISA Kits Complete plate-based kits across sandwich, competitive and rapid formats, with a validated protocol and standard curve reagents included.
Browse ELISA Kits →
Chemiluminescent CLIA Kits Chemiluminescent detection in place of a colourimetric readout, giving a wider dynamic range and lower limit of detection. Formats mirror our sandwich ELISA kits.
Browse CLIA Kits →
Build Your Own Antibody Pairs A matched capture and detection antibody set, supplied without a pre-coated plate, for labs setting their own plate, diluent and blocking conditions.

Where they're used

Typical applications

✓ Biomarker quantification in serum and plasma
Our ELISA and CLIA kits quantify cytokines, growth factors and other circulating proteins in serum and plasma samples, against a validated standard curve.
✓ Hormone quantification
Kits across our ELISA and CLIA ranges are used to measure hormone concentrations in serum, plasma and other biological fluids for research purposes.
✓ Protein expression in cell lysate and tissue homogenate
Our kits quantify target protein levels in cell lysate and tissue homogenate, supporting expression studies across research applications.
✓ Custom sandwich assay development
Antibody pairs let labs build a custom sandwich assay on their own plate, choosing their own sample diluent and blocking conditions.
