Sulfo-SANPAH is a heterobifunctional, water-soluble cross-linker combining a sulfo-NHS ester with a photoreactive nitrophenylazide. It reacts with primary amines and, after UV activation, forms covalent bonds to nearby substrates, making it suitable for immobilizing proteins and extracellular matrix components on polymer surfaces and hydrogels. Supplied as an orange-red solid with recommended frozen storage for long-term stability.
- Heterobifunctional cross-linker with amine-reactive sulfo-NHS ester.
- Photoactivatable nitrophenylazide enables UV-triggered covalent coupling.
- Water-soluble for direct use in aqueous buffers.
- Enables covalent immobilization of proteins and ECM to substrates.
- Supplied as a solid powder with stable storage at frozen temperatures.
- High purity for consistent conjugation performance.
