Collection: ELISA & Immunoassay Kits

Sandwich ELISA captures the analyte between two antibodies against different epitopes — signal rises with concentration, and it handles complex samples like lysates and supernatants well. Competitive ELISA suits small molecules with a single epitope; signal falls as analyte rises. Indirect ELISA detects antibodies in a sample, as in serology, using a labeled secondary antibody.

TriBioScience's Fast ELISA kits combine the sample and detection incubations into a single step, cutting a typical run from five or six hours to about two by the manufacturer's protocol. The readout stays plate-based — colorimetric or fluorometric — so no special instrumentation is needed beyond a standard reader.

Serum, plasma, cell culture supernatant, and tissue or cell lysates are all routine for sandwich formats; the kit datasheet lists validated matrices and recommended dilutions. Matrix effects are real — run a spike-and-recovery check when working with a sample type the kit was not validated for.

Only if the datasheet shows validated cross-reactivity — sequence homology alone is not enough, and most kits are species-specific by design. TriBioScience offers dedicated mouse kits for many targets, and a custom ELISA development service when no catalog kit fits.

Israeli researchers order TriBioScience ELISA and immunoassay kits through Danyel Biotech; quotes are answered locally, and our team can also route custom assay-development requests to the manufacturer.
