Multiplex immunoassays for biomarker research

Supremely Flexible. Highly Reliable.

DuoSet™ ELISA Development Systems kits offer a reliable, economical alternative to purchasing a ready-to-use ELISA or separate antibodies. Each DuoSet kit contains carefully selected and validated matched antibody pairs for accurate measurement of recombinant and natural proteins in biological fluids.

A mass-calibrated recombinant standard helps reduce assay variability and ensure long-term consistency.

  • Highly specific and optimized for superior performance
  • Adaptable across multiple platforms
  • More than 1,000 targets with new and novel targets across multiple species
  • Low cost per data point    

Proven Quality. Consistent Performance.

Consistent ELISA Development Using Matched Antibody Pairs

Specific and Consistent

Carefully selected antibody pairs combined with a mass-calibrated standard help ensure accurate performance and consistent results for data collected over time.

Affordable ELISA Kits

Economical ELISA

Economical 5 and 15 plate kit formats provide a low cost per data point while convenient ancillary reagent kits eliminate the need to buy each ancillary reagent separately.  

Affordable ELISA Development Kits in Multiple Species Options

Large Menu Across Species

Select from an expansive DuoSet kit menu that includes more than 1,000 ELISAs across 16 different species.

High Quality Low Cost ELISA Assays

Exceptional Immunoassay Quality

Application of our renowned Quantikine™ ELISA development practices helps ensure accurate, reproducible results over a broad dynamic range.

DuoSet ELISA Procedure Steps

DuoSet IC (Intracelluar) ELISA Development Systems

DuoSet IC (Intracellular) kits offer a fast, sensitive and economical method to detect and quantify intracellular factors in cell lysate samples. These signal transduction assays offer an attractive alternative to traditional Western Blot, providing up to 10 to 30 times more sensitivity.

DuoSet IC (Intracellular) Phospho-specific ELISA kits measure the amount of phosphorylated protein in cell lysates using activity using a specifically targeted detection antibody included in the kit. Targets include kinases, heat shock, apoptosis-related and genotoxic stress proteins.
