Cellular Technical Services

Cellular Technology Services (CTS) was a specialized contract research organization (CRO) that provided high-end flow cytometry and cell-based assay services to the biopharmaceutical and healthcare industries. Based in Gaithersburg, Maryland, the company focused on supporting clinical trials through complex immunomonitoring, biomarker discovery, and bioanalytical testing. CTS was particularly recognized for its expertise in multi-color flow cytometry and its ability to handle large-scale clinical trial samples under GCLP standards. In 2014, the company was acquired by Eurofins Scientific to bolster its global bioanalytical service offerings, and its operations were integrated into Eurofins Pharma Bioanalytical Services. The company's legacy continues as a core component of Eurofins' immunology and cell therapy support capabilities.
