Medchemexpress LLC Diamino polyethylene glycol | 956496-54-1 | 2000 Da | (C2H4O)nC2H8N2O | 500 MG
Supplier: Medchemexpress LLC HYW451406C500MG
NH2-PEG-NH2 (MW 2000) is a diamino-terminated polyethylene glycol reagent (average molecular weight 2000 Da) used for bioconjugation and PEGylation in research applications. The terminal primary amine groups enable fast coupling to activated carboxyls (for example, NHS esters), facilitating stable amide bond formation for protein, peptide, and small-molecule modification to enhance solubility and stability.
- Diamino-terminated polyethylene glycol suitable for bioconjugation.
- Average molecular weight 2000 Da for predictable PEGylation.
- Terminal primary amines react with activated carboxyls to form stable amide bonds.
- Improves solubility and stability of biomolecules.
- Reduces immunogenicity of modified proteins and peptides.
- White to off-white solid form for straightforward handling.
- Store sealed at 4°C, protected from moisture and light.
