About Us

Our history

CLS is a cell repository specializing in the global distribution of cell lines and cell-derived products to academia and industry, with more than 500 continuous cell lines from various tumors, tissues and species.

We were founded in 1998 with the mission of preserving research for future generations of scientists, providing researchers with authenticated cell cultures free of unwanted viral or bacterial contaminations.


We are directing our efforts towards a serum-free cell culture society. Already having grown more than 30 cell lines free of any serum additives, CLS is pursuing to adapt more than 100 cell lines to serum-free conditions by 2025 without altering their genetic markup, expression profile or growth characteristics. We do not only want to fight the reproducibility crisis but to preserve the future of science.
