K11
Based on 1 Customer Validation
K11 is an antimicrobial peptide. K11 is active against MDR/XDR K. pneumoniae isolates (MIC: 8-512 μg/mL), and inhibits bacterial biofilm formation. K11 can act synergistically with antibiotics (Chloramphenicol (HY-B0239), Meropenem (HY-13678), Rifampicin (HY-B0272), etc.) against drug-resistant K. pneumoniae. K11 has high thermal and wide pH stability.

Solvent & Solubility
H2O : ≥ 100 mg/mL (40.11 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). 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.
