- Full Name: Azide‑functionalized Poly(L‑Arginine) Hydrochloride
- Appearance: White/off‑white lyophilized powder
- Solubility: Highly soluble in water; forms clear aqueous solutions
- Key Features:
- Cationic polyamino acid with guanidinium side chains; positively charged in aqueous media
- Terminal azide (–N₃) group for click chemistry (CuAAC/SPAAC) with alkynes
- Cell‑penetrating properties; strong binding to nucleic acids/negatively charged surfaces
- Biocompatible, low cytotoxicity
- Main Applications:
- Click chemistry bioconjugation (linking to dyes, ligands, or biomaterials)
- Gene/drug delivery (polyplex formation with DNA/RNA)
- Cell culture coating & surface functionalization
- Layer‑by‑layer (LbL) assembly & biosensing
- Storage: −20 °C, desiccated, protect from light; store under argon if possible
