SPR /BLI analytical service

Biomolecular interaction analysis is used increasingly in drug development to kinetically characterize binding events of relevant components, including drugs and targets, antibodies and antigens or any pair of interacting molecules. Based on the Biacore 8K and ForteBio Octet platforms, ACROBiosystems provides biopharmaceutical R&D customers with complementary molecular interaction analysis services, including antibody screening, characterization, consistency evaluation, and biomolecule interactions that contribute to therapeutics development.

Platforms

Surface Plasmon Resonance (SPR) service

Biacore 8K

Surface Plasmon Resonance (SPR) technology is the leader and standard in the field of biomolecular interactions. SPR technology can provide unique insights to reveal the interaction between biomolecules, and help scientists understand the function of biomolecules.

Biolayer Interferometry (BLI) service

ForteBio Octet 96e

Biolayer Interferometry (BLI) technology can implement the quantitative and qualitative analysis of intermolecular affinity with the advantages of high sensitivity, high throughput and low sample volume.

ACROBiosystems can provide custom solutions to meet your following needs!
