     This work provides a verified protocol and comprehensive analysis for rapidly determining DBC [Dynamic Binding Capacity] for various molecules on capture chromatography resins using the FlowVPE spectrophotometer based on inline variable pathlength technology.    

 

Key Takeaways Include: 

  • Investigation of inline variable pathlength technology using FlowVPE for rapid determination of DBC on affinity resins for protein capture proved comparability with offline titer methods.

  • Variable pathlength technology for DBC determination can be successfully applied to different classes of monoclonal antibodies and fusion proteins.

  • This process enabled rapid screening of affinity resins and optimization of capture chromatography.

  • Use of inline variable pathlength technology eliminated the dependency on offline titer data and accelerated overall process development timelines with less cost.
