Surface Plasmon Resonance

PRESENTATION

The SPR/BLI platform provides a BIAcore/GE Healthcare life sciences instrument for the characterization of biomolecular interactions by Surface Plasmonic Resonance (SPR) detection.
SPR is an optical technique that measures changes in the refractive index on the surface of a metal surface. As they are dependent on the nature and mass of the constituents on the surface, this technique allows the detection in real time and without labelling of biological molecules.

With the Biacore T200, the technology is applied to the study of interactions between partners and the determination of kinetic constants of associations and dissociations (kon, koff), affinity constant (KD) or thermodynamic constants (dH, tdS).
The method is based on a biosensor on which a first molecule (the ligand) is immobilized, and the binding of the second partner (the analyte) is measured during its injection by a microfluidic system in a continuous flow of buffer onto the biosensor surface. The response is measured in real time (sensorgram) and is directly proportional to the mass density of the fixed biomolecules (1000 RU <-> 1 ng/mm2 <-> 10 mg/ml).
It applies to the characterization of molecular interactions involving small molecules and all classes of biological macromolecules (proteins, polysaccharides, lipids and nucleic acids).

GETTING STARTED GUIDE

A usage guide for the Biacore T200 is downloadable : GETTING STARTED GUIDE.

WHAT TO BRING FOR YOUR EXPERIMENTS

You need

Running buffer(s) in 1 L glass bottle.
Ligand samples at the highest concentrations (to be diluted in immobilization buffers).
Analytes samples at the highest concentrations (to be diluted in running buffers).
Regeneration buffers if known.
Biosensors/Sensochips series-S
Pipettes and tips (preferably checked and calibrated).
Necessary plastic tubes (Falcon, Eppendorf type tubes).
Any previous and relevant data and/or protocols.

Ordering consumables and kits
Users must provide consumables specific to their experiments.
Consumables must be ordered from Biacore/GE Healthcare Life Sciences (www.biacore.com).
No other biosensors/sensochips will be accepted.
For the Biacore T200, biosensor/sensorchips must be Series-S type.

WHAT THE PLATFORM PROVIDES

The SPR platform provides basic and common supplies for experiments on the Biacore T200 :

Biacore T200 instrument.
4°C refrigerator and -20°C -20°C -20°C freezer for sample storage.
Vortex and benchtop centrifuge.
P20/Tween-20 (added to your experiment buffers)
Immobilization kits for amine coupling methods.
Regeneration scouting kit.
Tubes and caps for Biacore T200.
External users who cannot bring laboratory supplies can borrow supplies from our laboratory (pipettes, tips, plastic and glass items).
If necessary, a UV/visible nanodrop spectrophotometer is available in our laboratory (room 520).
Filtered water solutions, instrument maintenance.

HOW MUCH TIME DO I NEED ?

The time required to fully characterize your interaction depends on your biological system, the strategy used, the time needed to optimize your experiences and the difficulties you may encounter...... It can vary from a few days to a few weeks.....
Here are some estimates of the time required for traditional methods :

Starting sequence : 20 to 30 min.
pH Scouting before immobilization by amine coupling : 30 to 60 min per ligand sample.
Immobilization by amine coupling : 45 to 60 min per sample.
Secondary capture : 20 to 30 min per sample.
Pilot analyses : ½ daily to several days depending on the number of sample injections at different concentrations, testing of several contact and dissociation times, several flow rates and regeneration conditions.
MCK/Steady State : 3 to 8 hours or more depending on kinetics and concentrations.
SCK : 2 to 5 hours depending on the kinetics.
Stop sequence : 30 min.

COMPUTING

The platform provides computers dedicated to the control of each instrument, the implementation of experiments, data acquisition and recording and data analysis,
The platform provides an additional computer with free access for data analysis and processing,
All computers are equipped with regularly updated software necessary for data monitoring and analysis,

ACKNOWLEDGEMENTS, PUBLICATIONS AND VALORIZATION

Collaborations
Collaborative projects require that platform staff co-author publications in peer-reviewed journals and other communications in which SPR or BLI data appear and in accordance with the terms previously discussed.

Service - made available
Users undertake to mention the platform and its staff in all publications or communications in which SPR or BLI data appear by mentioning the following sentence : "This work used the platforms of the Grenoble Instruct-ERIC center (ISBG ; UAR 3518 CNRS-CEA-UGA-EMBL) within the Grenoble Partnership for Structural Biology (PSB), supported by FRISBI (ANR-10-INBS-0005-02) and GRAL, financed within the University Grenoble Alpes graduate school (Ecoles Universitaires de Recherche) CBH-EUR-GS (ANR-17-EURE-0003).
