96-Channel Ultra High Throughput Octet System

  • Analyze up to 96 samples simultaneously - Perform your quantitation or kinetics experiments with unmatched speed. Quantitate up to 96 samples of an IgG sample in two minutes.
  • Perform a 32 x 32 epitope binning in less than eight hours - Use in-tandem, sandwich, or pre-mix assay designs to perform epitope binning. Complete a 32 x 32 epitope binning in less than eight hours.
  • Streamline workflows with automation – Automation-ready and robot-compatible for microplate and biosensor tray loading.

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

Octet HTX
Simultaneously reads 8, 16, 32, 48 or 96 wells

The HTX read head provides design flexibility that allows users to analyze, 8, 16, 32, 48, or 96 samples at a time allowing for customized throughput up to 96 samples.

Full plate off-rate ranking in minutes, not hours

The Dip and Read assay format allows off-rate analysis of clones to be performed rapidly even in crude samples using ready-to-use biosensors off the shelf.

96-well plate quantitation in as little as two minutes

IgG titer determination of a full 96-well plate can be completed in two minutes. In addition, sample plate compartment is compatible with 384-well plates allowing for even more throughput.

32 x 32 epitope binning in less than eight hours

With the HTX, analysis of epitope binning matrices can be completed in record time, with 32 x 32 in less than eight hours. A powerful epitope binning analysis software enables easy visualization of data sets and provides a flexible data matrix that can accommodate a variety of cross-blocking formats.

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

The Octet HTX utilizes Dip and Read™ technology with the read head dipping into samples in a plate format. With no fluidics involved, Octet systems are highly robust.

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
