Biological Activity
Kemptide is a synthetic construct of a substrate for cAMP-dependent protein kinase (PK). Different types of intact cells catalyze the phosphorylation of Kemptide in the presence of extracellular ATP and cAMP with Km values of 3-4 uM for Kemptide[1]. Kemptide is a synthetic peptide substrate derived from pyruvate kinase[2].

Solvent & Solubility
H2O : ≥ 100 mg/mL (129.55 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.

It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
PKA activity is measured in pools of 10 oocytes at various stages of maturation using the SignaTECT cAMP-Dependent Protein Kinase (PKA) Assay System. Measurements of basal PKA activity are performed in the absence of exogenous cAMP, whereas measurements of total (cAMP-stimulated) PKA activity are performed in reaction buffer containing 0.025 mM cAMP[2].
