Immunoassay Reagents and Kits

Kits, substrates, and reagents for a variety of immunoassay procedures, including ELISA, singleplex immunoassays, and multiplex immunoassays, that are ideal for the quantification of target antigens; substrates available in colorimetric, chemiluminescent, or chemifluorescent varieties.

We offer a variety of products for enzyme-linked immunosorbent assays (ELISA or EIA) including plates, reagents, and kits to help you detect and quantify peptides, proteins, antibodies, and hormones.

ELISA is an analytical method based on the highly specific interaction between an antigen and an antibody. For this assay, an antigen is attached to a solid surface, to which an antibody-enzyme complex is linked. When a substrate is added and incubated with the other materials, it produces a measurable product.
