The Octet® R2 System is a multipurpose instrument for early research and discovery that characterizes protein interactions and measures active protein concentrations in complex mixtures. It is highly sensitive and can analyze small molecules as small as 150 Da in size, and their larger binding partners to determine accurate kinetics rates.

  • Affordable High-Quality Interaction Analysis: Octet® R2 System is a cost-effective option for academic and biotech labs. It provides high-quality interaction analysis without the use of microfluidics, making it perfect for binding kinetics. The 2-channel system is suitable for low-throughput applications, providing a low-cost entry point without compromising performance.
  • Versatile and Multipurpose: This system analyzes protein-protein and protein-small molecule binding interactions, important in early research and discovery. It can measure active protein concentrations or potency in complex mixtures
  • Scalability and Flexibility: The Octet® R2 is a scalable system that can be upgraded as per the lab requirements. The system comes with two channels initially, but it can be easily field-upgraded to a 4-channel or 8-channel system. This upgrade can be done in a single visit by a field service engineer, eliminating the need to exchange the old model
