Your research destination is just ahead
And we've got the immunoassays to help you get there
You're a researcher. You take the road less traveled. Along the way, you may encounter roadblocks or detours, but you don't let them stop you—because you're determined to discover new ways of understanding the world. Problem-solving is in your blood. That's why Thermo Fisher Scientific has designed Invitrogen™ immunoassay products—to provide you with the innovative tools you need at every stage of your research journey.




Whatever road your research takes,
we've got you covered
For over 32 years, we've provided antibody-based, target-specific protein quantitation tools for life science research.
Enabling the parallel analysis of cellular, protein, and genetic processes, our comprehensive and flexible portfolio of products and services includes the reliable reagents, kits, panels, and support you need for target-specific protein quantitation in the fields of immunology, inflammation, neuroscience, stem cell research, cancer, cell biology, and more.
Our broad portfolio of Invitrogen™ immunoassay kits covers:


A comprehensive portfolio of innovative products
for target-specific protein quantitation
We offer a wide range of Invitrogen™ immunoassay products, including high-sensitivity assays; ELISA kits optimized for convenient and sensitive quantitation of a wide range of targets; multiplex assays that enable simultaneous measurement of multiple proteins per well; and reliable, prematched antibody pair kits for enhanced ease of use and cost savings.
A quick tour of our portfolio


- Referenced in over 3,000 publications
- Flexible portfolio of products-including build-it-yourself ELISAs, coated ELISA kits, and uncoated ELISA kits
- Thoroughly validated to meet the high standards you expect from Invitrogen™ products
- Manufactured with stringent quality controls and a high correlation across the portfolio of immunoassays to enable excellent quality, reproducibility, and consistency of results


- Flexibility—add to existing panels or build your own panels; run up to 65 targets simultaneously from our ready-to-use panels or up to 80 targets from our custom panel services
- Time and cost savings—rapid profiling of multiple proteins in a single well can save 250 hours or more in just one experiment when using a large multiplex panel
- High correlation—both across panel sizes and with coated ELISA kits (R2 > 0.9), enables researchers to confidently compare data between experiments
- More than 16 years of experience—developing assays for the Luminex® platform, providing a comprehensive offering of multiplex reagents and instruments to researchers

- Small sample consumption—use 2–5 μL of sample; for example, use 2 μL vs. 150 μL with other methods
- Fast, easy workflow—no wash steps, and only 2 hours from sample to answer
- Broad dynamic range—5 logarithmic units or greater helps minimize sample dilutions to help ensure falling within the range
- No proprietary instrument to purchase—runs on any real-time PCR instrument
