Surface Plasmon Resonance imaging (SPRi) Service

Creative Peptides is a leading biotechnology company which has the expertise in providing SPRi service for customers. Creative Peptides’ sophisticated equipments, advanced technologies and highly experienced staffs are available to help you monitor a large variety of bio-interactions, such as antibody/antigen, peptide/antibody, DNA/DNA, antibody/bacteria etc. With the help of highly experienced staffs, Creative Peptides can provide the most professional SPRi service with fast turnaround time to customers worldwide.

SPRi (Surface plasmon resonance imaging) is a real-time, label-free, and high-throughput technique which is used to study biomolecular interactions based on detecting the refractive index changes resulting from molecular binding. More specifically, SPRi has been developed to examine affinity between biomoleculars, screen biomarkers and detect biopsy specimens.[1-4] With years of experience in the SPRi field, Creative Peptides can offer the most affordable and professional SPRi service to fulfill your advanced research needs in various applications.
