P4SPR™ Series

Core Technology​​

Basic thin film SPR found in most benchtop devices capable of detection in complex media such as serum, plasma, cell lysates, or wastewater. 

Flexible Design​​

Adaptable from injection to sensor. Comes with two injection models with multiple options to meet your research needs

Rapid Data Processing

Intuitive software providing key data for biosensing and protein interaction characterization in real time.

With P4SPR, we were able to establish optimal immobilization conditions of SARS-CoV-2 spike and nucleocapsid within 2-3 SPR runs. Having the device at our bench also really helped comparing our SPR results against ELISA.
