Two new surface plasmon resonance kits are available that enable the analysis of lipids and membrane proteins with peptides and small molecules. The ProteOn LCP sensor employs memLayer technology to selectively and stably capture lipid assemblies. The native lipid–like environment of the chip surface where proteins are captured ensures good quality data. The ProteOn GLC lipid kit allows researchers to study interactions of membranes with proteins and peptides. Biopharmaceutical researchers use the kit to capture lipoparticles containing membrane protein drug targets of interest. Antibodies against those drug targets are then screened to measure binding kinetics.
