SPR as a Service

Don't wait for the core facility. Go mobile.

Core facilities are bottlenecks. Booking windows stretch weeks, turnaround is slow, and you lose control of your experiment. Mobile SPR changes that — we bring the instrument to you, run the experiment on-site, and hand you the data before we leave. No shipping samples. No reformatting for another lab's workflow. Just results.

Mobile SPR service — Affinité Instruments on-site testing
5 minutes per run
Each SPR measurement completed in 5 minutes — rapid screening without sacrificing data quality.
20+ conditions in 2 hours
Full process condition screening — static SPR covering your entire variable space, same day.
1 m² bench space
The entire setup fits on a single square meter of temporary bench space. No facility modifications needed.
"Within the production facility, the team completed each SPR run in 5 minutes, screening over 20 process conditions in under 2 hours."

Case Study

Rapid assessment of manufactured biomolecule quality — in a single day.

A biomanufacturer needed real-time production monitoring without disrupting the facility. We ran static SPR directly on-site using the P4SPR — screening 20+ process conditions and generating binding data in under two hours. Results correlated strongly with active molecular concentrations, supporting real-time production decisions.

When kinetic characterization was needed, the P4PRO followed. Full kon, koff, and KD — same day, same visit.

Know Your Method

Kinetic vs. static SPR — which one do you need?

Not every experiment needs full kinetics. Static SPR is fast, flexible, and ideal for screening — crude media, large sample sets, concentration estimates. Kinetic SPR delivers the complete picture: association and dissociation rates, affinity constants, mechanistic detail. The right choice depends on the question.

Static SPR (P4SPR)
Screen 20+ conditions in 2 hours. Yes/no binding, concentration, affinity estimates. No microfluidics.
Kinetic SPR (P4PRO)
Full kon, koff, KD. Controlled flow, clean curves, publication-ready data.
Both, same day
Static first for screening. Kinetic to characterize hits. One visit, complete picture.
