ELISA Kits

Our ELISA kit range covers sandwich, competitive, Ready-to-use and uncoated formats 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, with assay times ranging from 3-4 hours.

Choosing the right ELISA kit

ELISA kits quantify proteins, peptides, hormones and other biomolecules in complex biological samples. The right format depends on your analyte's size and abundance, the sensitivity you need, and how much hands-on time your protocol allows.

  • Sandwich ELISA kits Matched capture and detection antibody pair, suited to low-abundance analytes in complex samples.
  • Competitive ELISA kits Preferred for small, low molecular weight targets where a two-antibody sandwich format is not possible.
  • Ready-to-use ELISA kits Save time with prediluted detection reagents. No need to dilute the antibodies, which come ready to apply.

Ready-to-use ELISA

Single-wash protocol delivers results in 90 minutes. Recombinant capture and detection antibodies support high specificity and lot-to-lot consistency.

Sandwich ELISA

Two-antibody capture and detection for sensitive, specific quantification across complex sample types. Standard 4 to 5 hour protocol.

View kits

Competitive ELISA

Inverse signal format suited to small molecules, hormones and metabolites below the size threshold for sandwich assays.

Types of ELISA kit

Sandwich ELISA kits

Sandwich ELISA kits use two antibodies against different epitopes of the same target: one immobilised on the plate to capture the antigen, the second conjugated for detection. Our sandwich ELISA range covers over 2,000 analytes across 20+ species, with a standard curve range and sensitivity stated on every datasheet.

Competitive ELISA kits

Competitive ELISA kits measure antigen concentration through signal inhibition rather than direct capture, producing an inverse standard curve. This format suits low molecular weight targets such as hormones and small metabolites that cannot support two non-overlapping antibody binding sites.

Ready-to-use ELISA

Save time diluting reagents with our Ready-to-use ELISA kits. Both capture and detection antibody have been prepared in advance, so you spend less on preparation.

Matched antibody pairs

Matched antibody pair kits supply a titrated capture antibody and biotinylated detection antibody, without a pre-coated plate. This lets you set your own plate, sample diluent and blocking conditions for a custom sandwich ELISA.
