About Cytek Biosciences, Inc.

Cytek Biosciences, Inc. is a company dedicated to cell analysis solutions, offering advanced tools that facilitate scientific progress in both biomedical research and clinical settings. Their primary offerings include the Aurora and Northern Lights spectrum flow cytometers.

Complementing these, the Aurora Cell Sorter system utilizes full spectrum profiling technology to broaden the range of potential applications in cell analysis. Beyond instrumentation, Cytek provides essential reagents and kits.

They also offer a 25-color immunoprofiling assay, a ready-to-use solution for pinpointing major human immune cell subpopulations like TBNK cells, monocytes, dendritic cells, and basophils. To streamline laboratory operations, the company offers automated micro-sampling and sample loader systems. These automated plate loaders are engineered to integrate seamlessly with the Aurora and Northern Lights systems. The intuitive SpectroFlo software accompanies these systems, simplifying the workflow from quality control through to data analysis. Cytek also provides comprehensive customer support resources. Cytek's diverse client base includes pharmaceutical and biopharmaceutical companies, academic research institutions, and clinical research organizations. The company distributes its products through a direct sales force and dedicated support teams in North America, Europe, China, and the Asia-Pacific region.
