Real-World Application

Evaluating kinetic parameters 

Evaluating kinetic parameters using SPR, including kon, koff and KD is crucial in biosensing. These parameters offer insights into the strength and specificity of molecular interactions, allowing precise characterization of binding events in real-time. Moreover, SPR-generated data is seamlessly compatible with TraceDrawer, facilitating comprehensive analysis and visualization. Additionally, SPR software often allows effortless data export to other platforms, enhancing flexibility and interoperability in data analysis workflows.


Quantification of proteins

The P4 series streamlines protein quantification and activity monitoring with precision and reproducibility. The automated data analysis tools in our ezControl software facilitates dynamic profiling and accurate quantification of protein activity, enhancing research efficiency and insights saving both time and resources for subsequent experiments.

Analysis in complex media

Affinite Instruments collaborated with researchers and agencies to develop assays informing immune response to SARS-CoV-2 and vaccine development. During this project, scientists validated our SPR against ELISA in complex media such as plasma, serum, and dry blood spots. Notably, a pseudo-neutralization assay was validated to evaluate the humoral response to SARS-CoV-2 in clinical serum samples, greatly advancing our understanding of the virus's immune response and vaccine effectiveness.
