Bio-Rad Launches New Protein GLH Sensor Chip for Small Molecule Applications

Bio-Rad Laboratories, Inc., a multinational manufacturer and distributor of life science research and clinical diagnostics products, today announced a new GLH sensor chip for its ProteOn™ XPR36 protein interaction array system. The chip, which generates a high analyte signal through its high ligand activity and binding capacity, is expected to deliver an improved surface plasmon resonance (SPR) signal compared to other commercially available surfaces. The amine coupling chemistry and polymer layer of the GLH sensor chip is similar to the ProteOn GLC and GLM chips, allowing exceptional ligand binding across a wide pH range.

“Customers who require high sensitivity detection can benefit significantly from using the GLH sensor chip and our ProteOn XPR36 protein interaction array system, especially for any small protein molecule or protein-protein research where the analyte response is low,” said Renee LeMaire-Adkins, Ph.D., Bio-Rad Marketing Manager, Protein Interaction Technology.

The ProteOn GLH sensor chip, consisting of a highly extended mixed polymer layer for maximum binding capacity, is designed for general amine coupling. The chip is optimized for protein-small molecule interactions as well as protein-protein interactions, where extremely high sensitivity is a primary concern. Beta testing has been successfully conducted in several customer laboratories in the U.S., Australia, Japan, and Europe.
