Introduction

SensorgramSurface Plasmon Resonance (SPR) is a powerful technique to measure biomolecular interactions in real-time in a label free environment. While one of the interactants is immobilized to the sensor surface, the other are free in solution and passed over the surface. Association and dissociation is measured in arbitrary units and displayed in a graph called the sensorgram.
Biomolecular Interaction Analysis is not limited to proteins. Interactions between DNA - DNA, DNA - protein, lipid - protein and hybrid systems of biomolecules and non-biological surfaces can be investigated.

KD Assistant

The KD assistant is a small program to assist with the optimization of kinetics runs. The program can calculate the maximal analyte concentration to be used from one manual analyte injection. The input consists of the initial binding rate (slope), the response of the analyte injection and the analyte concentration. The program deals also with the capturing level of the ligand and adjusts the analyte concentration accordingly. Goto Software

New on the SPR-Pages

There is a new chapter on the SPR-Pages. Look at Sensorgrams and learn all the important parts of a sensorgram. Learn how to distinguish a good from a bad sensorgram. How to optimize your sensorgram. In addition, learn how to report your result in such a way that everyone believes that you did your experiments properly. Finish this chapter with a quiz!

 

SPR-Pages book

All the information of the SPR-Pages and more in one book. The book contains the theory and the practical approach of preparing samples and sensor chips, performing the experiment and analyzing the results.
In addition, the book has more background information and experimental strategies are explained. The book contains more in-depth information than the website.
This is a valuable resource near your SPR-instrument!

BiaMethodWriter

BiaMethodWriter is a program to write the Biacore 2000 and 3000 automation methods in a more interactive way. The program uses pop up menus and dialog boxes to fill in the different parts. Remembering these odd parameters is not necessary any more.

The program calculates vial and buffer volumes and estimates the total runtime. The report function creates an overview of the method and a vial layout with required volumes. Colored text formatting gives a better overview of the method and makes it easier to find errors. read more ...

Zhou et al. developed a gravity driven SPR sensor. This power-free flow injection system is easy to use and the internal reference compensates for flow fluctuations. The miniature and power-free flow injection system would open the possibility to build a miniature system for point of care testing. Goto referenence...

Springer et al introduces single surface referencing. A single functionalized surface is split into the detection and reference channel to which complex sample (detection) and complex sample mixed with biomolecules binding to the analyte and thus inhibiting the binding of the analyte to the functionalized surface (reference) is introduced.
