Our product portfolio primarily includes conventional analyzers such as the LongCyte™ and FongCyte™ series, the full-spectrum analyzer CytoStellar™, and automated sample preparation systems. In addition, Challenbio has developed a growing portfolio of NMPA-cleared IVD reagent products for clinical immunophenotyping, including a 6-Color TBNK Lymphocyte Subset Detection Kit for routine immune status monitoring, T Cell Deep Subset Panels for granular characterization of naïve, memory, and effector populations, and an 8-Plex Cytokine Detection Kit for multiplexed quantification of key inflammatory markers. Together with our instrument platforms, these IVD reagents form a fully integrated clinical flow cytometry solution—from sample preparation through data acquisition and analysis.

We cater to various fields including clinical diagnosis, biotherapy, biological research, pharmaceutical R&D, environmental science, and food safety monitoring, serving nearly 1,000 customers worldwide. Currently, the company has obtained ISO 9001 and ISO 13485 system certifications and is committed to developing high-end flow cytometers and ancillary products.
