4arm-PEG-NH2, (4arm PEG amine, MW 10,000) is a multi-arm PEG polymer with four reactive amine groups. It is reactive with active ester, such as NHS, TFP, and PFP. The HCl salt increases stability and solubility for versatile applications.
Key Features:
- Structure: A 10,000 MW PEG core with four amine-terminated arms, perfect for crosslinking and bioconjugation.
- Reactivity: The amine groups quickly react with carboxyls, aldehydes, and NHS esters, forming stable amide bonds.
- Applications:
- Crosslinking: Ideal for forming hydrogels and biomaterial scaffolds.
- Bioconjugation: Easily attaches proteins, peptides, or drugs for drug delivery.
- Surface Modification: Enhances biosensor and medical device surfaces.
- Solubility: The HCl salt improves water solubility, broadening its use in aqueous environments.
Summary:
4arm-PEG-NH2, HCl Salt (MW 10,000) offers reactive amine groups for efficient crosslinking and bioconjugation. Enhanced solubility and stability make it ideal for drug delivery, hydrogels, and surface modification in medical and biotech applications.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
