High Throughput Platform for Biologics Development

From IgG titer to epitope binning, the Octet RED384 system offers label-free molecular interaction analysis with state-of-the-art high throughput platforms that facilitate the rapid characterization and development of biologics drug molecules.

The high detection sensitivity and throughput of the Octet RED384 system have also made it a favorite for small molecule library screening and analysis of large cross-competition binding matrices. Target ligands can be batch immobilized onto biosensors and returned to the biosensor tray for re-use in future experiments, thus extending the number of uses for each biosensor, preserving valuable ligand, and maximizing flexibility in experimental design.

  • Analyze up to 16 samples simultaneously
  • Streamline workflows with automation - Automation ready and robot compatible for microplate and biosensor tray loading.
  • GxP packages available - Available as complete packages with 21 CFR Part 11 software and IQOQPQ kits, protocols and services for regulatory compliance.
Octet RED384
Supports 96-well and 384-well microplate formats

Use up to 384 samples in one 384-well microplate for kinetics analysis

Microfluidics-free Dip and Read format reduces assay time and maintenance cost

The Octet RED384 system utilizes Dip and Read™ technology with the read head dipping into samples in a plate format. With no fluidics involved, the Octet 384 system has more uptime and a lower cost of maintenance.

ELISA Conversion

ELISAs are known for having variability in results, susceptibility to human error, and slow times-to-results. High throughput Octet systems are designed to overcome those limitations.  Convert your ELISA assay into an Octet assay.

Read Application Note

Epitope Binning

Epitope binning studies rely on the sequential binding of two antibodies to an antigen, and are performed using dozens of antibody pairs in cross-competition matrices. The Octet system excels at these large-scale studies due to assay speed, throughput, and exceptional reproducibility

Protein Contaminant Testing

Protein contaminants are a major hurdle to overcome during the production of biopharmaceuticals. The Octet platform's rapid high throughput protein analysis combined with the anti-CHO HCP and Residual Protein A kits  provide biologics developers with a rapid and easy to use technique for contaminant testing.
