L-Cystine dihydrochloride 30925-07-6
Key Properties & Advantages ofL-Cystine dihydrochloride
-
Solubility Boost
- Free L‑cystine: ~0.11 mg/mL in water (25 °C)
- L‑cystine dihydrochloride: ~50 mg/mL in 0.5 M HCl
- Critical for preparing concentrated stock solutions in cell culture.
-
Stability
- Less prone to oxidation and degradation than free cysteine.
- Maintains activity during long‑term storage and sterilization.
-
Biological Activity
- Serves as a source of cysteine for protein synthesis and glutathione (GSH) production.
- Acts as an Nrf2 inducer, reducing reactive oxygen species (ROS) and protecting cells from oxidative stress.
- Supports disulfide bond formation, essential for protein folding and stability.
