Why ATGen

We are the Manufacturer

What differentiates us from most proteins and antibody providers on the market is that we manufacture them ourselves. This means, we can ship them right away because we have them in inventory and we can help you troubleshoot. It most likely also means that our products will be less expensive.

We are trustworthy

The other great thing about ATGen is that we offer a very personalized and customized service. On top of that, we guarantee all our products. If any of our products don’t work as indicated, we will replace them or give a refund right after some quick troubleshooting.

We listen

As for how we choose our proteins/antibodies, we collaborate with many professors, some of them stockholders, and we obtain suggestions from them or from our clients. Which means, if you can’t find what you are looking for, please let us know, we would love to hear your thoughts.

Our fields of expertise

Life Science

We are consistently increasing the number of products we develop as you can confirm by browsing through our web catalog. We are always working on improving the quality of our products. The list of activity-tested proteins keeps growing. Our monoclonal antibodies are of the best quality, and in our effort to always improve we regularly add immunohistochemistry pictures to our antibodies.


We have started expanding into the diagnostic market, which is why we are currently in the process of obtaining the ISO13485 certification for in vitro diagnostic devices. We have developed H1N1 antibody detection test (rapid kit (KFDA approved) and ELISA kit (for Korean Commercial Labs and for research) and are currently working on other diagnostic devices. We believe it won’t be long before we have strong products ready for the market.

Technology platform: Stable Protein

In 2002, ATGen first developed a technology to enhance a protein’s stability and resistance to environmental stresses. We believe that this technology could prove to be a great enhancer to therapeutic proteins, vaccines, or to protein applications in the cosmetic industry. However, the cost of clinical studies for these applications has delayed this technology’s full potential.
