pI Marker Vial

Advanced Peptide pI Markers for icIEF Workflows

  • Lyophilized format: improved stability, easier storage, and transportation
  • Comprehensive pI range coverage: suitable for a wide variety of proteins and monoclonal antibody projects
  • Dual detection compatibility: supports both 280 nm UV absorbance and fluorescence detection
  • Exclusive fluorescent pI markers: including pI 5.28 and pI 8.18 etc, enabling risk-free method transfer from UV-based to fluorescent icIEF workflows
  • CPB Resistant Markers: peptide markers designated with * are resistant to Carboxypeptidase B (CPB)
  • Strong platform compatibility: optimized for CEInfinite icIEF systems and fully compatible with other mainstream commercial cIEF/icIEF platforms
