Ligand Immobilization in Protein Interaction Studies — An Unattended Amine Coupling Protocol with Automatic Coinjection Activation
Amine coupling is the most commonly adopted technique to bind proteins to biosensor chips. Because of the possibility of the amine coupling reagents reacting with each other, these have to be premixed just before the injection and injected independently. Here are some tips to automatically coinject these reagents.

Good data processing practice ensures that protein interaction experiments using a surface plasmon resonance (SPR) system will yield the clearest possible results. Here we present tips for understanding and processing SPR sensorgrams when using Bio-Rad’s ProteOn™ XPR36 protein interaction array system.
Analyzing protein interaction data using a surface plasmon resonance (SPR) system can be complicated. This user guide describes how to analyze SPR data to obtain kinetic and equilibrium constants, as well as sample concentrations.
This appendix to “Guide to SPR Data Analysis on the Proteon™ XPR36 System” gives information on the data set export using ProteOn Manager™ Software.
Using Bio-Rad’s PDQuest Software to Generate a Match Rate between 2-D Electrophoresis and Western Blotting
2-D electrophoresis followed by immunodetection of protein spots using western blotting is adopted commonly in proteomics studies. Here we present step-by-step instructions for obtaining accurate overlaps between the gel and the blot using the PDQuest 2-D gel analysis software.
A Novel Biotinylated Ligand-Capture Method with Surface Regeneration Capability for Label-Free Biomolecular Interaction Analysis
Ligand-capture approaches using biotin as an affinity tag are often utilized in biomolecular interaction analyses with surface plasmon resonance (SPR) biosensors. However, a drawback to using biotin is that it makes surface regeneration of SPR sensor chips difficult. Here is a strategy that facilitates surface regeneration when using biotinylated ligand-capture approaches to SPR analysis.
Analyzing Binding Kinetics with Surface Plasmon Resonance Complemented with Direct Mass Spectrometry on the Same Sensor Chip
Surface Plasmon Resonance (SPR) is an optical phenomenon that is used for the label-free analysis of the binding of any two molecules in real-time.
Learning to use analysis software can be time-consuming and following a manual can be challenging.
