About us

Structural analysis of membrane proteins is still a huge challenge. This is particularly true for pharmaceutically relevant human membrane proteins, e.g. transporters or G-protein coupled receptors (GPCRs). The design of efficient drugs depends on the availability of membrane protein structure information.
Our strength - We are service providers as well as manufactures.
The Cube Biotech team shares more than 40 years of experience on membrane protein expression, purification, and crystallization. We founded Cube Biotech in 2012 to make this experience available to the pharmaceutical and biotech industry, as well as to the academic environment. To ensure the highest quality in our service offering, we at Cube Biotech make our own protein purification resins and crystallization products. We buy raw materials, cell-free lysates and detergents from selected suppliers dedicated to the highest quality.
Research & Development

Our R+D and production site is located in Monheim, Germany, close to Cologne. We serve customers in many countries from here, and also interact closely with our distributors and OEM partners.
Cube Biotech Inc. USA

In 2013, we founded our US subsidiary in Wayne, PA, with a warehouse and customer support team to provide optimal service to our customers in North America.

Whatever we use in our services, we also make available to the community as consumables, accompanied by dedicated protocols and handbooks, tips and tricks for success.
As a small company, we are flexible enough to fulfill most needs for small and large volumes, customized resins and kits. Contact us to see how we can support your membrane protein project.
