Proteintech Group Acquires Manufacturer of Human Cell-Expressed Proteins, HumanZyme

ROSEMONT, Ill.–(BUSINESS WIRE)–#Proteintech–Proteintech Group, the benchmark in antibodies, today announces an
agreement to purchase HumanZyme. HumanZyme is a leading manufacturer of
recombinant human proteins. Their proprietary human cell-expression
system generates authentic human proteins that have greater biological
activity and stability than competitors’ systems. With this acquisition,
Proteintech Group further solidifies its position as a leading
manufacturer of antibodies, proteins and ELISA kits.

“Proteins are the past, present, and future of biology and medicine. And
the future is using real human proteins to answer lingering questions
about who we are and deliver therapies that can bring hope to patients
suffering a myriad of diseases. With the acquisition of HumanZyme, we
now have the best human proteins in the world to complement our catalog
of high quality antibodies,” said Dr. Jason Li, CEO, Proteintech Group.

Dr. Mark Azam, VP of R&D and Operations of HumanZyme added, “We are
excited to join forces with Proteintech. Both of our teams have a
relentless commitment to quality. Producing the best antibodies and
proteins will lead to breakthrough results in medicine.”

“Life science to date has been using proteins derived from bacteria and
Chinese hamster ovary cells. There is a limit to how much we can
understand humans using non-human tools,” said Li, “With authentic human
proteins and specific antibodies, however, the sky is the limit.”
