How it works

SoluLINK technology uses an innovative linker-based strategy to chemically join two molecules to form a single hybrid with a novel function. The chemistry is based on the reaction of an aromatic hydrazine (HyNic) with an aromatic aldehyde (4FB), which forms a stable bis-aryl hydrazone bond. This UV-traceable chromophore helps ensure experimental success with direct quantification to:

  • Determine of the number of linkers incorporated on each biomolecule prior to conjugation
  • Monitor and record the conjugation reaction in real time
  • Measure of the number of linkages formed in the conjugate and the precise number of biomolecules or ligands attached
