KALA
Based on 1 Customer Validation
KALA is an amphiphilic peptide that forms an α-helical structure at physiological pH. KALA modifies a plasmid DNA-encapsulating liposomal membrane and is used as a fusogenic peptide in order to achieve effective liver targeting and transfection of DNA via galactose receptors.

Solvent & Solubility
H2O : ≥ 50 mg/mL (15.97 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light, under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
