Description

Nh-(m-Peg8)2 CAS NO 2055013-64-2 is a high-purity, heterobifunctional polyethylene glycol (PEG) derivative, specifically designed as a versatile linker and spacer molecule for advanced bioconjugation and nanotechnology applications. Its core value lies in providing a hydrophilic, flexible, and biocompatible bridge to modify biomolecules, surfaces, and nanoparticles, enhancing solubility and reducing immunogenicity. This product is essential for researchers and manufacturers in the pharmaceutical, diagnostics, and materials science sectors who require precise and reliable PEGylation reagents for drug delivery systems, diagnostic assays, and hydrogel fabrication.

Application

• Bioconjugation and PEGylation: A key reagent for attaching drugs, proteins, peptides, or fluorescent dyes to nanoparticles or other biomolecules to improve pharmacokinetics and stability.
• Drug Delivery System Development: Used as a functional linker in the synthesis of antibody-drug conjugates (ADCs), polymer-drug conjugates, and liposomal formulations.
• Diagnostic Assay Reagents: Employed to conjugate detection molecules (e.g., enzymes, antibodies) in ELISA, lateral flow assays, and other immunoassay platforms.
• Surface Functionalization: Modifies the surface of quantum dots, magnetic beads, and other nanomaterials to introduce specific reactive groups for further coupling.
• Cross-linking Agent for Hydrogels: Serves as a water-soluble cross-linker in the creation of biocompatible hydrogels for tissue engineering and controlled release applications.
• Biomaterial Modification: Used to graft PEG chains onto medical device surfaces or implantable materials to create non-fouling, protein-resistant coatings.

Quality Control

Our Nh-(m-Peg8)2 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive bioconjugation work. Certificates of Analysis (COA) detailing purity, moisture content, and functional group assay are available upon request to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture absorption. For long-term storage, consider under an inert atmosphere.
