Valylleucine TFA
Based on 1 Customer Validation
Valylleucine (Val-Leu; H-Val-Leu-OH) TFA is a branched-chain dipeptide that can enter cells independently via bacterial dipeptide transport systems, and is hydrolyzed by dipeptidases to release Val and Leu. Valylleucine TFA, as a model peptide, has its α-amino pK determined to be 7.90 by combining FDNB reaction kinetics with potentiometric titration.

Solvent & Solubility
H2O : ≥ 50 mg/mL (145.21 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.
