SPEAR Technology: An immunoassay workflow with the sophistication of nucleic acid testing paradigms

Successive Proximity Extension Amplification Reaction (SPEAR) technology offers unprecedented sensitivity for protein biomarker measurement while maintaining a simple, wash-free workflow. These unique features position SPEAR as a game-changing tool for developing blood-based biomarker assays, addressing long-standing challenges in neurology.

In this session, Dr. Feng Xuan explains the development of SPEAR and how it fundamentally differs from conventional ultra-sensitive immunoassay technologies. Key performance data using SPEAR to quantify and differentiate several low-abundant neuro biomarkers, as well as current applications and future possibilities for SPEAR are also discussed.
