Description

Bis-Aminooxy-Peg7 is a high-purity, heterobifunctional polyethylene glycol (PEG) linker featuring two aminooxy groups, enabling efficient conjugation to carbonyl-containing molecules. This compound is critical for creating stable, site-specific bioconjugates and cross-linked materials with precise control over structure and function. It is primarily needed by researchers and manufacturers in bioconjugation, pharmaceutical development, and advanced material science for applications requiring controlled molecular assembly.

Application

• Bioconjugation and Protein Modification: Site-specific conjugation of proteins, antibodies, or peptides via their N-terminal or engineered ketone/aldehyde groups.
• Drug Delivery System Development: Synthesis of PEGylated drug conjugates and linkers for controlled-release formulations.
• Hydrogel and Biomaterial Cross-linking: Creating biocompatible networks and scaffolds for tissue engineering and 3D cell culture.
• Surface Functionalization: Immobilization of biomolecules onto sensor chips, nanoparticles, or diagnostic platforms.
• Antibody-Drug Conjugate (ADC) Linker: Serving as a cleavable or non-cleavable bridge between a cytotoxic payload and a targeting antibody.
• Oligonucleotide and Small Molecule Conjugation: Attaching labels, probes, or therapeutic agents to oligonucleotides or other carbonyl-containing compounds.

Quality Control

Our Bis-Aminooxy-Peg7 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and consistent performance for critical research and development applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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. Due to its hygroscopic nature, the container should be sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent moisture absorption and degradation. Keep away from strong oxidizing agents.
