On May 28, 2024, Cytek Biosciences (Nasdaq: CTKB) announced that its 1-laser and 2-laser 6-color TBNK reagent cocktails received approval from China's National Medical Products Administration (NMPA) for clinical use. These reagents, used in the Cytek Northern Lights-Clinical (NL-CLC) cell analysis systems, aid in diagnosing and monitoring immune-related conditions such as immunodeficiencies, autoimmune diseases, infections, and cancers. The NMPA clearance marks the first clinical 1-laser based 6-color TBNK assay supported by Full Spectrum Profiling (FSP) capability. This approval enhances Cytek's market presence in China, offering new opportunities and strengthening its competitive edge. The Cytek NL-CLC systems are designed to perform optimally in multicolor environments, and their onboard volumetric meters reduce testing costs by eliminating the need for counting beads.
