Thiol‑Poly(L‑lysine)‑Thiol, MW 3.3 kDa (HS‑PLL‑SH)
- A linear homopolymer of L‑lysine, dithiol‑terminated at both ends, with molecular weight ≈ 3300 Da.
- Positively charged, water‑soluble cationic polypeptide capable of condensing DNA/RNA and adhering to negatively charged surfaces.
- Terminal thiol groups (‑SH) enable disulfide crosslinking, Michael addition, and conjugation with maleimide, OPSS, or vinyl groups.
- Often used in redox‑responsive hydrogels, self‑assembled micelles, bioconjugation, and gene delivery systems.
- Typically stored under inert atmosphere at −20 °C to prevent oxidation.
