Surface plasmon resonance (SPR) instruments measure binding kinetics, affinity and active concentration between molecules without labels. They are widely used to characterize antibody and ligand interactions. Buyers compare throughput, meaning how many samples are measured at once (standard flow, array type or imaging), the smallest analyte the instrument handles, whether GxP compliance is needed, and bench space. Angle-scanning systems also cover thin films and nanoparticles. The products we track are listed below, with the maker and Japanese seller of each.
“Where to buy in Japan” shows only sales relationships we have confirmed on the company’s or the distributor’s own website. “Not yet confirmed” means we have not checked yet, not that the product is unavailable in Japan. Product names link to the maker’s own page.
