HT-SPR eliminates the need for large quantities of samples and multiple days of experiments to characterize drug candidate FcγR binding. A rich panel of receptors from all relevant species in replicate, up to hundreds of discrete measures, can be kinetically defined against a drug candidate in less than a day. The number of drug candidates undergoing detailed FcγR binding characterization can be dramatically increased compared to traditional approaches.

  • Unmatched Throughput: Characterize binding against every available FcγR in one shot
  • Superb Data Quality: Gold standard binding kinetics and affinity
  • Reduced Assay Costs: Nearly 30-fold reduction in cost per measurement compared to traditional biosensor platforms

Case Study: Dragonfly Therapeutics

HT-SPR redefined characterization of FcγR binding for Dragonfly Therapeutics. Not only was data quality nearly indistinguishable from their current biosensor, but using the LSAXT they were able to complete a full characterization in less than a day which historically would take an entire week.
