The S-HyNic (succinimidyl-6-hydrazino-nicotinamide) heterobifunctional crosslinker is fundamental to Solulink's proprietary linker technology. Sulfo-S-HyNic is a water soluble analog of S-HyNic. The S-HyNic analog reacts with primary amines on proteins (amino group of lysine) or amino-modified oligonucleotides or surfaces, introducing a HyNic (6-hydrazinonicotinamide) linker that forms stable covalent conjugates with biomolecules possessing 4FB (4-formylbenzamide) incorporated linkers. Sulfo-S-HyNic is recommended for incorporating HyNic linkers on amino-surfaces or biomolecules. This linker is particularly useful for biomolecules or surfaces that are sensitive to organic solvents such as DMF or DMSO.


Solulink's proprietary linker technology is based on the use of two complementary heterobifunctional linkers:  

  • S-HyNic crosslinker or its analog is conjugated to biomolecule 1 through primary amines on proteins, oligos, peptides, or surfaces.
  • S-4FB (succinimidyl-4-formylbenzamide) linker or its analog is conjugated to biomolecule 2 through primary amines on proteins, oligos, peptides, carbohydrates, or surfaces.
  • HyNic-modified biomolecule 1 is incubated with 4FB-modified biomolecule 2 to form a conjugate.

The result is two biomolecules conjugated through a UV-traceable and stable bond (bis-arylhydrazone) with measurable absorbance at 354 nm. Thus any two proteins, regardless of molecular weight, can be efficiently conjugated.

Solulink Advantages

  • Catalyzed Conjugation – Faster kinetics for greater efficiency and yields
  • Quantifiable – Conjugate bond is UV-traceable for simple and direct quantification
  • Stability – 10 times more stable than any other conjugation linker
  • Specificity – Two-linker method avoids homoconjugate formation
  • Efficient – >80% efficient linker - biomolecule conjugations
  • Robust – The conjugate bond is stable to 92˚C and to pH values ranging from pH 2.0–10.0
