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.

Novel Liposome-Capture Surface Chemistries to Analyze Drug-Lipid Interaction Using the ProteOn™ XPR36 System

Surface plasmon resonance (SPR) biosensors offer a label-free technique for profiling biomolecular interactions, including those between drugs and liposomes. Here we describe the novel surface chemistries that make capturing liposomes possible, and explore the application of the liposome capturing kit in analyzing liposome-small molecule interactions.
