Our background

Here at Xell AG, we are distinguished by our skilled and motivated team of employees. They each have highly specialized scientific backgrounds, solidifying our strong focus on technology and innovation.

Emerging from the Institute of Cell Culture Technology at Bielefeld University, Germany, in 2009, Xell AG (formerly TeutoCell AG) has grown to become an independent and privately financed biotech company dedicated to cutting-edge innovation and developing expertise.

With more than 20 years of hands-on experience in cell culture technology, Xell has drawn from its academic and technological knowledge to become a key partner in the design and distribution of cell culture solutions. We launched our first commercial products for CHO and hybridoma cell lines in 2010, and since then, Xell has continuously developed new tools for mammalian cell cultivation, benefiting from strong partnerships in industry and academia.

2015 saw Xell move to a new facility, and this gave us the additional capacity we needed to expand our portfolio of innovative off-the-shelf media. In 2019, a brand-new manufacturing facility was brought into operation, supporting large-scale production of liquid and dry powder formulations such as cell culture media, buffer and medical products. Today Xell has three main independent business divisions that work together closely:

  • Production of liquid and dry powder formulations – from cell culture media and feeds for CHO, HEK , BHK and hybridoma , to buffers and medical products
  • Analytics of spent media, food, feed and other sample types
  • Research and development – cell culture and process optimization services to enhance our customers’ knowledge and performance

Besides our ISO 9001 certification (Quality management system) obtained in 2019, we are working on our ISO 13485 certification (Medical devices — Quality management system) for 2021.

We collaborate with companies and universities around the globe to broaden our portfolio and create new and exciting initiatives to support your ideas.

ACYTE Biotech Pty Ltd is an Australian- based biotech company specializing in proprietary technologies in mammalian cell engineering and cell culture. ACYTE aims to reduce bottlenecks in early stage biopharmaceutical development by providing a suite of SuperCHO® technologies to streamline the path from discovery to clinic. Two key technologies include:

  • Epi-CHO, a high-yielding CHO cell based transient gene expression system
  • Stable cell line generation using a robust, well-characterized and high yielding expression system which meets regulatory expectations for clinical and commercial applications

ACYTE has a wealth of experience in stable cell line development combining its proprietary suspension adapted cell line, XL-99, with versatile, highly stringent expression vectors and high throughput clone selection platform. The system is ideal for generating cell lines in a rapid time frame which are scalable for clinical and commercial applications.

BIBITEC Gesellschaft für Prozessentwicklung mbH is specialized in the production and purification of proteins (e.g. hormones, mAbs) derived from mammalian cell cultures.One major achievement was an erythropoietin (EPO) project that involved the process development and the GMP- compliant production of an EPO biosimilar for use in phase III clinical trials.The entire production and purification process was successfully transferred for large-scale production leading to one of the first successful approvals of a biosimilar in Europe.

In 2012 BIBITEC became part of Nordmark Arzneimittel GmbH & Co. KG, Uetersen. In cooperation with Nordmark and other validated partners BIBITEC provides all activities from “gene to product” including cell line and process development, GMP production, fill-and-finish and analytics.

InVivo is an ISO 9001 certified contract manufacturing organization (CMO) dedicated to the development and production of monoclonal antibodies and expression of recombinant proteins for research, diagnostic and pre-clinical use. Since 1998 InVivo provides cost-effective outsourcing solutions for a large number of satisfied clients.

A wide range of different hybridomas have been cultivated in InVivo’s proprietary serum-free media ISF1. Production under serum-free conditions enables high productivity without the drawbacks of serum-containing processes, e.g. contamination with bovine IgGs. High cell density fermentation using different cell retention systems yields up to 500 mg antibody per liter per day. After a one step purification using recombinant protein- A/G our monoclonal antibodies are of highest purity.

Furthermore InVivo offers the complete range of modern recombinant protein expression techniques. Starting from synthetic cDNAs the protein can be expressed in bacteria, insect or mammalian cell lines. To meet customer ́s needs for mammalian derived proteins on short order we offer transient transfection using HEK- and CHO- cells. This fast and productive alternative is often favored over stable cell line development.
