Company Overview
Xell is an innovative and agile biotech company providing high-quality products and services for cell culture applications. While having a focus on the development and manufacture of chemically defined cell culture media, we continuously extend and improve our portfolio of related cell culture and analytical services.

READY-TO-USE CULTURE MEDIA AND FEEDS
Biopharmaceutical companies, research institutes and CMOs world-wide use Xell’s culture media and feeds for the production of diagnostic and therapeutic proteins, viral vectors and vaccines. For the most commonly used mammalian cell types, Xell has developed a catalog of readily available products. This includes amongst others cost-efficient all-in-one solutions for transfection and transient production. The various products are chemically defined, free of animal components, and available as liquid for R&D as well as dry powder with certified quality for large-scale GMP manufacturing. Our current portfolio includes solutions for the following cell types:
- CHO
- HEK293 (and other human cell lines)
- BHK, MDBK, MDCK
- Hybridoma
- CAP®

CUSTOMIZED MEDIA DEVELOPMENT
Our custom media accommodate for the particular requirements of individual client cell lines. Our rational development approach combines a superior culture media platform with metabolic models and powerful spent media analysis to deliver tailored solutions in the most efficient way. A large number of successfully completed projects has helped us to gain a reputation as a reliable partner in this field.
