Proteintech Slogan throughout the years

Just as scientists grow throughout their years of research - undergraduate studies, to postdoctoral candidacy, to PhD and beyond - Proteintech has grown as well. Born from an incubator lab at the University of Illinois at Chicago, the Proteintech that exists today looks much different. But regardless of the building we inhabit, the team members at Proteintech have never stopped in their pursuit of knowledge. Not only do we strive to learn more about scientific technology, but we also are hard at work learning how to better serve you, the scientists.

Just as our capacity and goals change throughout the years, so does the message we want to communicate to you; A.K.A our slogan. Take a look down memory lane at how the Proteintech's slogan has changed throughout the years.

2002 : Antibodies for every human protein.

Originating from one of our first, and highest reaching, goals - our very first slogan simply stated what we were striving for: antibodies against every human protein known to man.

2005 : Your silent partner in research.

After establishing a base of customers, and learning more about the ideal role of an antibody supplier, Proteintech established this slogan. Hoping to communicate our goals of investing as much thought and care into your research as you do. 

2015 : Antibodies people trust.

In 2015, our slogan shifted once more. We realized something that was lacking in the antibody supplier world, trust. The idea that you can rely on a company to follow through on their promises, and be there with a real person to help you when you need it most. This is the core concept behind our 2015 slogan.

2016 : The benchmark in antibodies.
2017 : From our bench to your bench.

Finally, we come to where Proteintech stands today. As scientists ourselves, we know how much mental and emotional effort you put into your research. This slogan strives to communicate that we will always be there for you with quality and support because of our own experiences at the bench each day. 


We see every customer as our collaborator in research and want to thank you for your contribution to life science research. When you publish a paper featuring any Proteintech antibody or ChromoTek Nanobody, we will reward you with one of the following products for free:  

  • One full-size (100ul or 150ul), unconjugated Proteintech primary antibody of your choice 

  • One full-size (100ul) ChromoTek IgG antibody of your choice 

  • One 10ul size ChromoTek Nanosecondary product of your choice

2021 marks Proteintech’s 20th anniversary with 100,000th citation of their products

CHICAGO--(BUSINESS WIRE)--Proteintech Group, a leading manufacturer of antibodies and related products, is celebrating the 20th anniversary of its founding. To celebrate the achievements and challenges of the past years, Proteintech will host special events throughout the year with its customers, collaborators, and employees while still looking forward to future opportunities.

“While we are proud of our progress as a company over the past couple decades, we are most proud of what our technology has done in the hands of scientists. We’ve seen more than 100,000 citations of our products since our company establishment”

“Over the years we have witnessed countless discoveries and we couldn’t be prouder of everything our customers have achieved. We want to thank all of our customer for their tireless efforts and sacrifices to advance scientific discovery,” Dr. Jason Li, CEO

Proteintech Group was founded in early 2001 by a small group of scientists including its current CEO, Dr. Jason Li. The founders set out with a vision to produce an antibody for every single protein coded in the human genome. Comprehensive coverage of all human gene products is a massive undertaking, but critical because it is difficult for researchers to predict which targets may be required to further scientific studies. With antibodies for two-thirds of the human genome, Proteintech has the largest self-manufactured target coverage of all antibody companies.

100,000 success stories to date

“While we are proud of our progress as a company over the past couple decades, we are most proud of what our technology has done in the hands of scientists. We’ve seen more than 100,000 citations of our products since our company establishment,” said Dr. Li. “We are excited about the future and how we can continue to help scientists apply the new technology we are working on to help people.”

Company expansion and cGMP facility

As Proteintech has continued to expand their own antibody, protein and ELISA kit product lines, they have welcomed other producers of high-quality tool providers for scientists. In April 2018, Proteintech acquired Humanzyme™, a Chicago-based manufacturer of human cell-expressed proteins, and shortly thereafter opened their cGMP facility in 2019. Using a proprietary HEK293 cell expression technology, HumanKine™ proteins are authentic human proteins with human glycosylation providing an optimized biological activity. Furthermore, they can be easily transferred from research grade, preclinical and process development to GMP grade for manufacturing in clinical trials and for commercial products.

In 2020, Proteintech acquired ChromoTek, a Munich-based manufacturer of camelid, single-domain antibodies, also known as nanobodies. These high-performance recombinant reagents will help Proteintech address opportunities and challenges in single cell analysis, super resolution imaging, and multiplex assays.

Over the last 20 years, Proteintech has grown in their global reach. With locations in the US, UK, Germany, Singapore, China and Japan, Proteintech is able to provide fast delivery around the world. Now with over 300 employees worldwide, Proteintech is setting their sights on continuing to support the future of science with quality, transparency, and customer needs in mind.
