Leadgene Leadgene



Leadgene offers you a new platform, FOPPR™ INB-D200, for affinity analysis between antibodies and antigens.

It is with more favorable prices and shorter time of analysis.

FOPPR™ affinity analysis service

The unique & patented FOPPR™​​​​​​​ Technology is combining optical waveguides with noble metal nanoparticles for the sensitive and reliable detection of molecules. In FOPPR™, gold nanoparticles (AuNPs) are in close proximity to an unclad optical fiber. As light propagates within the optical fiber, total internal reflection (TIR) results in an evanescent field that induces the AuNPs to undergo particle plasmon resonance (PPR).
When target-analytes interact to AuNPs - conjugated ligands, it will lead to a change of refractive index near the sensing surface. The extreme sensitivity of this optical property to
changes in the surrounding environment makes FOPPR™ an ideal technology for monitoring real-time interactions between a wide range of molecular species, including but not limited to organic drugs, oligonucleotides, proteins, and viruses.
