Biological Activity
PKI(5-24) is a 20-residue peptide has been synthesized that corresponds to the active site of the skeletal muscle inhibitor protein[1].
PKI(5-24) inhibits phosphotransferase activity of the mutant cGMP kinase with higher potency than that of wild type, with Ki values of 42 μΜ and 160 μΜ, respectively[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
H2O : 25 mg/mL (11.25 mM; Need ultrasonic)
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.
