Biosensing Instrument introduces new option for SPRm 200 and BI-4500 Series SPR

September 25, 2018

Tempe, AZ

Biosensing Instrument Inc. (BI) introduced today a new option to fully automate your surface plasmon resonance (SPR) workflow assays.   The new syringe pump allows continuous flow so there is no stop during sample reloads, thus increasing the quality of your data.   The pump has an in-line degassing system and through the BI software control, buffer exchange is possible for up to four buffer sources.   This new option can be combined with the awards winning SPRm 200 or BI-4500 series systems.

SPRm 200, a 2018 New Product Innovation Award recipient from Frost & Sullivan and a 2018 R&D 100 Award finalist, combines SPR and bright field microscopy technologies and it is the only scientific solution on the market that enables label-free in vitro measurement of binding affinity and kinetics of cell membrane proteins in their native environment.  By providing the ability to study molecular interactions using cells grown on the sensor chip, this novel system redefines the frontier of SPR technology.

The BI-4500 series, a Kretschmann configuration based SPR, is a 2017 R&D 100 Award winner that delivers high quality binding response for low immobilization and small molecule (<100 Da) detection.  It has an autonomous sample preparation and delivery for convenient hands-free operation and its modular innovative design gives researchers with optimal flexibility to choose amongst various analysis modules for electrochemistry, liquid and gas phase SPR applications.
