Antibody Pairs

Our antibody pair range supplies a concentrated capture antibody and a biotinylated detection antibody for building your own sandwich immunoassay. Each pair is validated against a native or recombinant immunogen, with datasheets covering formulation, purification and storage, so you can set your own plate, diluent and blocking conditions.

What's in an antibody pair

Antibody pair kits give you the building blocks of a sandwich ELISA without a pre-coated plate, so you control the surface, diluent and detection chemistry.

Capture antibody Unconjugated and titrated for coating your own plate.
Detection antibody Biotinylated and matched to a non-overlapping epitope on the same target.
