The Residual Protein A (RPA) kit is a ready to use setup enabling for sensitive, accurate quantitation of leached Protein A in bioprocess samples while maintaining a simple workflow. The kit utilizes a validated sample treatment method for dissociating Protein A from antibodies that does not require boiling, neutralization or centrifugation steps. Dip and Read RPA biosensors with pre-immobilized chicken anti-Protein A antibody are sequentially dipped into treated samples, buffers, and detection antibody arrayed in 96-well microplates to create a microscale immunoassay on the biosensor tip. Signal detection occurs in real-time at the secondary antibody step without the need for conjugates or enzymatic reactions.

Key Benefits:

  • Specificity - Designed to detect recombinant Protein A constructs and MabSelect SuRe
  • Sensitivity - Accurate quantitation down to 100 pg/mL recombinant Protein A
  • Unattended operation - Automated detection with minimal hands-on time
  • Throughput - Analyze 96 samples in under 2 hours on the Octet HTX system Not intended for diagnostic use.
