Description

Sulfo-Sanpah is a heterobifunctional, photoreactive crosslinking agent widely used in biochemical research and bioconjugation. Its core value lies in its ability to create stable covalent bonds between proteins and other molecules, such as nucleic acids or solid surfaces, under controlled UV light activation. This product is essential for researchers and manufacturers in the fields of biotechnology, pharmaceutical development, and diagnostic assay production who require reliable and efficient conjugation tools.

Application

• Protein Immobilization: Covalently attaching antibodies, enzymes, or other proteins to microplates, biosensor chips, or chromatography resins for assay and purification development.
• Affinity Labeling: Studying protein-protein or protein-ligand interactions by crosslinking binding partners for subsequent analysis.
• Nucleic Acid-Protein Crosslinking: Investigating DNA-binding proteins or creating stable complexes for structural studies.
• Biomaterial Fabrication: Modifying surfaces of medical devices or tissue engineering scaffolds to enhance biocompatibility and cell adhesion.
• Antibody-Drug Conjugate (ADC) Research: Serving as a model linker in early-stage research for connecting cytotoxic payloads to targeting antibodies.
• Diagnostic Reagent Development: Conjugating detection enzymes (e.g., HRP) to antibodies or other probes for ELISA and lateral flow assays.

Quality Control

Our Sulfo-Sanpah is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic confirmation of structure, to ensure consistency and performance for sensitive research applications. Certificates of Analysis (COA) with detailed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic and strictly light-sensitive nature, the product should be handled under low-light conditions and allowed to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
