Cell lines for your research – we culture, control and conserve

Made in Germany - Traditional German Quality

CLS Cell Lines Service GmbH

CLS Cell Lines Service was founded in 1998 in order to support the scientific community with respect to conserve cell lines. This cell bank (cell repository) covers about 500 cell lines, which have been isolated from various tissues, tumours and species, with the focus on human cell lines. Every year new cell lines are included in the cell bank, mostly by licensing in or by new cooperation. 

As the cell lines are controlled on a daily basis by microscopy, many data have emerged which resulted in the publication of the ‘Atlas of Living Cell Cultures’ in May 2013.

Additionally, due to the conservation and quality control of the cell lines, CLS GmbH has extended its skills and therefore offers a couple of services such as Mycoplasma testing or conducting transfections. Furthermore, CLS manufactures products out of the cell lines i.e. genomic DNA, RNA, whole cell lysates and snap-frozen cell pellets.

CLS Mission

Permanent as well as primary cell lines are recognized as a major part in fundamental research.
The increasing comprehension and knowledge of the manifold of processes going on inside each single cell enhances the understanding of the molecular processes of diseases such as cancer.

Only then new therapies and drugs can be developed. Furthermore, the usage of cell cultures in vitro to clarify fundamental questions can replace an increasing number of experiments in vivo using animals.

CLS GmbH aim to support the scientists who are working in the Life Sciences, Biology, Biochemistry, Biotechnology and Medical Diagnostics in the daily routine using cell cultures.
