Octet® BLI Label-Free Detection Systems for Biomolecular Interactions Analysis

Unprecedented Time and Cost Savings For Kinetics, Affinity, and Concentration Assays

Octet® systems enable real-time, label-free analysis for the determination of kinetics, affinity, and antibody/protein quantitation. Based on Bio-Layer Interferometry (BLI), this fluidics-free instrument platform offers a number of advantages over traditional label-free techniques like Surface Plasmon Resonance (SPR). The Octet® BLI platform also provides robust monitoring of biomolecular interactions to overcome limitations in throughput, performance, and cost associated with traditional technologies such as ELISA or HPLC. These fluidics-free, low maintenance and sensitive systems increase lab productivity, reduce costs, and shorten experimental timelines. 

With our latest additions to the Octet® portfolio, the Octet® R Series, you can choose between a 2-, 4- or 8-channel model (Octet® R2, R4, or R8) to balance budget and throughput needs. The Octet® R2 and R4 offer field upgradeability to futureproof your research and your investment. 

Accelerate your research with systems that offer:

  • Higher Throughput - Protein quantitation in as little as two minutes, and parallel processing of up to 96 samples. 
  • Fast Time to Results – Automated analysis for faster time to market and faster publications.
  • Real-time Analysis – Binding interactions are continuously monitored as they happen. Don’t miss out on subtle kinetic behavior patterns.
  • Crude Sample Compatibility - Analytes can be measured in crude, unpurified mixtures such as cell lysates or hybridoma supernatants.  Octet® systems tolerate glycerol and up to 10% DMSO.
  • Ease of Use – Simple, integrated user interface designed for biologists. Spend less time learning instrumentation and more time deriving insights.
  • Low Total Cost of Ownership – Low maintenance system has no fluidics modules to clog, so no downtime while waiting for replacements
