High Precision Streptavidin (SAX) Biosensors

For High Precision Quantitation and Kinetic Analysis

  • Rapid and stable capture of biotinylated molecules
  • High precision quantitation and kinetic analyses
  • QC-tested to meet precision-controlled coefficient of variation (CV) specification of <4%

The High Precision Streptavidin Biosensor (SAX) was specifically developed and qualified for applications in drug discovery and quality control labs that have stringent requirements for assay precision and robustness in quantitation and binding kinetics characterization assays.

For quantitation assays involving non-Ab protein analyte, biotinylated capture molecules loaded on SAX biosensors may be used to generate data with high precision. When running assays for effector function analysis, antibody engineering, quality control studies or wherever else binding kinetics characterization is performed, the best assay performance can be attained using SAX biosensors. The actual performance in customer's assays may vary depending up on the choice of sample matrix, ligand and analyte, and other assay conditions.
