As a manufacturer of ELISA kits, Exosome isolation kits, antibodies, proteins and related reagents, our only mission is to provide the best products and related custom service to researchers so that they can have a good starting for the next breakthrough. CUSABIO`s high quality has been guaranteed by many published literatures in all kinds of famous journals, such as Science, Nature, Cell, Developmental Biology, Molecular Cell, Genes & Development, and so on. Now, the publications citing our products has reached more than 4,800, and hundreds of publications are updating every year.

Kits

CUSABIO has a sound platform for the development of assay kit, mature antigen-antibody research and development system. Assay kits offered by CASABIO are mainly two types, including ELISA kits and exosome isolation kits. We are proficient in a variety of ELISA technologies such as the double antibody sandwich method, double antigen sandwich method, direct competition ELISA method, indirect competition ELISA blocking method, indirect ELISA method, and other methods. And fine affinity purification technology for the production of Exosome Isolation Kits is also adopted.

Combined with the diagnostic kits development team, we are able to develop the ELISA kits with clinical diagnostic levels and make the quality in the leading place worldwide. Exosomes have been one of the research hotspots in recent years, and the separation technology of exosomes has been constantly updated and improved. After continuous improvement and repeated testing, we also developed high purity, high yield, and high-efficiency exosome isolation kits. CUSABIO now offers a broad range of ELISA kits covering over 6,000 different assay targets and two Cell Supernatant Exosome Isolation Kits. If you are interested in these kits, you can go to the corresponding product page for more details.

Antibodies

CUSABIO offers 60,000+ antibodies that are specific to a variety of species and can be used in multiple applications. Furthermore, the number of CUSABIO antibodies is continuing to grow at a rate of 1000 per year.
