More than 1,000 protein-specific ELISA kits

Ready-to-use Invitrogen ELISA kits are optimized for convenient and sensitive quantitation of a wide range of targets in various sample types, including human, mouse, rat IgG, cytokines, phosphorylated proteins, beta amyloids, extracellular and intracellular targets. Pre-coated and coat-it-yourself sandwich ELISA kits include capture and detection matched antibodies, standards, buffers, diluents, and detection reagents. Specialty ELISA formats and configurations are also available.


We offer several varieties each of coated and uncoated ELISA kits, including those based on Invitrogen Instant ELISA Technology, validated for particular levels of sensitivity, formatted as sandwich and competitive ELISAs, or optimized for a various sample types. Our portfolio of ELISA kits now includes products previously sold under the Affymetrix eBioscience brand, now part of Thermo Fisher Scientific.

The new, combined Invitrogen ELISA kit product family encompasses a greater range of available analytes, species, and formats. Especially noteworthy additions are the Instant ELISA kits and expanded line of immunoglobulin and isotyping kits.

Complete and validated.

These kits include antibodies, standards, detection reagents, and 96-well plates that are precoated with the capture antibody.

Affordable and convenient.

These kits contain matched antibody pairs, standards and detection reagents but require users to coat the capture antibody themselves.

Customize to your needs.

Develop, test, and validate your own direct or sandwich ELISA by selecting your own antibodies, reagents, plates, and other assay components.
