TES sodium
Based on 1 Customer Validation
TES sodium is an excellent hydrogen ion buffer. TES sodium has characteristics such as an appropriate dissociation constant, a low metal-binding constant, and high water solubility. TES sodium can be used in the research of mammalian cell culture, viruses, and so on.

Biological Activity
TES (0.1 M) sodium has pKa values of 7.92, 7.50, and 7.14 at 0°, 20° and 37°, respectively, and the concentration of its saturated aqueous solution at 0° is 2.6 M[1].
TES (6-50 mM; 11-14 days) sodium in a closed culture environment is similar to or even more effective than the NaHCO3-CO2-buffered medium in terms of colony-forming efficiency, colony size, and cell morphology of several mammalian cell lines (HeLa S3, KB, BHK 21-Cl3, 3Y1-B Cl-1)[2].
TES (25-50 mM; 14-19 days) sodium has a similar efficiency to NaHCO3-CO2-buffered medium and the required time is shorter in the SV40 virus plaque assay with monkey kidney CV-1 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
H2O : 250 mg/mL (995.10 mM; Need ultrasonic)
DMSO : 83.33 mg/mL (331.69 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.
