Based on the advanced and comprehensive Mempro™ nanodisc analysis platform established for years, Creative Biostructure offers high-quality surface plasmon resonance (SPR) technology service for nanodisc production.
SPR technology has quickly turned into a standard technique in the biotechnology and pharmaceutical industries, because of its excellent characteristics that enable the identification of the interactions of almost any molecular system, including nanodiscs. This technique is broadly applied to research protein–ligand interactions taking place in a thin fluid layer directly bind to a gold-coated biosensor chip, which constitutes the heart of microfluidic flow cells. The ligand, one of the interaction partners, is required to be settled at the biosensor surface. While the analyte, the other partner, is transfused into the cell at a variety of concentrations and flows across the biosensor. SPR measures the variation in refractive index an ultra thin boundary layer, which is immediately proportional to a quantity of protein in this region, that is, immobilized ligand and bound analyte.
