Exazym® Immunoassay Signal Amplification Kits

Cavidi offers a range of Exazym® reagents and kits for convenient and fast integration of BOLD into new or already existing immunoassays. Our BOLD technology requires no specialized equipment and is applicable to most immunoassays. Whether you're using common colorimetric, fluorescence, or chemiluminescent detection, Exazym® seamlessly integrates with existing plate readers and analyzers. The amplification step is fast and can be performed at room temperature.

How Exazym® Kits are Used

The products are designed in a modular fashion to accommodate the needs of academic and industrial research groups as well as immunoassay kit producers.

Step 1 Conjugate Antibodies Link an oligo-dT primer to a detector antibody or use ready-to-go antibody pairs.

Exazym® ClickChem Conjugation Kit

Provides all reagents needed to attach the oligo-dT primer to the secondary antibody.

Exazym® Antibody Pairs

Use our pre-conjugated antibody pairs and leave the conjugation work to us.

Step 2 Amplify the Signal Boost sensitivity with a polymerase reaction.


Exazym® Polymerase Reaction Kit

Contains the reagents and buffers needed, as well as the protocol to perform the polymerization reaction.

Step 3 Detect the Signal We offer three different detection options.


Exazym® Detection Kits

Provide everything you need for detection. Select from Biotin, APC, or PE when ordering.

As a first-time user of Exazym®, you will need a kit from each of step. Once you begin using Exazym®, you will use the kits at different rates. We supply them as three separate kits in two plate sizes to give you flexibility. For bulk orders, please contact Cavidi’s Customer service team.
