SPR Contract Services

SPR expertise is now
within reach.

Backed by 80+ peer-reviewed publications

Publication-grade binding kinetics without the instrument, the specialist, or the queue. You bring the molecules and the question. We bring everything else.

How it works

From first call to binding data.

No procurement cycle, no training course. You describe the question — we handle the rest.

Carrying the Affinité Instruments SPR case to your lab

You describe the question

What binds, how tightly, and why it matters.

We design the assay

Surface, flow, controls. We handle it.

We run it — at your lab or ours

Sensitive samples? We bring the instrument to you. No shipping, no couriers.

You get the data

Kinetics, sensorgrams, interpretation.

Our approach

SPR, the Affinité way.

We run both static and flow SPR on the same platform. Quick yes/no on binding? Static mode, minutes, ELISA-like. Full kinetics with dose-response? Flow mode, publication-grade sensorgrams, real-time fitting.

Most CROs make you choose. We run both, on instruments we designed lensless — 10x smaller optical path, nothing to align, nothing to drift. Research-grade SPR that fits in a backpack.

Who we are

We didn't just learn SPR.
We built the instruments.

AffiBio is the services arm of Affinité Instruments. The people running your experiment are the same people who chose the optics, formulated the surface and wrote the fitting code. No layer we can't explain, none we can't fix.
