Feature Highlight: Sense in Complex Samples: Solvents & Detergents



  • DMSO is often needed to keep high concentrations of small molecule compounds soluble during early stage drug discovery. This is a problem for common optical kinetic binding platforms, as DMSO negatively impacts optical properties.
  • Agile R100 leverages an orthogonal technology called Field Effect Biosensing (FEB), an electrical technique that is unaffected by changes in optical properties. The platform easily senses in optically challenging samples such as buffer containing 10% DMSO.
  • In this technical note, we share Agile R100 kinetic binding data (kon, koff, and KD) from the interaction of 3 small molecule compounds dissolved in 10% DMSO binding with their respective targets – 2 GPCRs solubilized in additional detergents and a cytokine protein.

Background Info

Equilibrium Analysis Guide


Excerpt: In equilibrium analysis, the concentration of T is held constant and the concentration of A is varied over a series of equilibrium binding experiments. Equilibrium binding experiments with increasing concentrations of A are repeated until the plateau value of the binding curve no longer increases, indicating that T has been saturated (i.e. no more AT can form).

Assay Development Tips for COOH Agile Biosensors


The sensitivity and specificity of a biosensor are directly related to the availability and functionality of immobilized capture molecules, but ambient compounds may also nonspecifically contribute to the sensor response, thereby decreasing the signal-to-noise ratio (SNR). Blocking and quenching steps are used in biosensors to reduce the contributions from background compounds that interfere with the measurement signal. Several aspects of biosensor functionalization can be optimized to drive down the effects of nonspecific interactions and increase the SNR for targeted detection, critical to sensing low concentrations of target analyte with low signal. This technical note demonstrates possible blocking and quenching techniques useful for assay development with the COOH Agile R100 biosensor.

Application Notes

Affinity Ranking of SPD304, Evans Blue, and Trypan Blue to TNFα Using Agile R100


Affinity ranking is critical to optimizing the relationship between a target protein and a potential drug compound during the hit-to-lead optimization phase of drug discovery. In this application note, Agile R100 characterizes the activity of the target protein TNFα interacting with the small molecule drug compounds, SPD304, Evans Blue, and Trypan Blue in order to rank order by affinity.

Technical Notes

Kinetic Binding Analysis on Agile R100


Biosensors are used in a variety of fields to characterize biomolecular interactions in real-time. The results of these interaction studies inform the development of the next generation of diagnostics and therapeutics and provide insights into the mechanisms by which pathogens evolve and infect. Label-free assays are particularly useful in these endeavors because they eliminate both the chance of the added label interfering with the native binding chemistry and the additional chemistry steps to attach the label to the molecule under investigation. This technical note provides an overview of the kinetic binding data collected by Agile R100.

Comparison Studies

Agile R100 versus MicroCal iTC200 Kinetic Binding Data


Agile R100 is a graphene biosensor with unprecedented functionality, providing label-free, real-time kinetic binding data. As a novel technology, Agile R100 is compared to MicroCal iTC200 to demonstrate its benefits compared to a standard kinetic binding analysis tool, isothermal titration calorimetry (ITC). In this study, kinetic binding data between the two instruments is compared by measuring Rho guanosine triphosphate hydrolase enzyme (GTPase) interacting with GTPase activating protein (GAP). The association and dissociation binding rate (ka and kd, respectively) and dissociation constants (KD) are reported. Agile R100 has a precise binding affinity measurement (KD = 1.35 ± 0.06 µM), comparable to MicroCal iTC200 (KD = 2.7 ± 0.3 µM), while also obtaining ka and kd values. Additionally, Agile R100 uses up to 30 million times less sample material and up to 30 times less sample volume and can perform 2.5 times more measurements in a given workday compared to MicroCal iTC200.
