What is the pH value of your probenecid solution (Cat# 20062)?
Posted June 13, 2019
With our current probenecid reagent we are experiencing very poor water solubility. I see you offer a probenecid 25 mM stabilized aqueous solution and a water soluble probenecid sodium salt.
Could you provide the pH values of the solutions when probenecid (Na+ salt) is dissolved in pure water and in the recommended HHBS buffer, respectively? As well as the pH value of your probenecid 25 mM stabilized aqueous solution?
Answer
ReadiUse™ probenecid, sodium salt
- 25 mM in HHBS, pH=7.5; 2.5 mM in HHBS, pH=7.5
- 25 mM in H2O, pH=11.0; 2.5 mM in H2O, pH=9.5
ReadiUse™ probenecid 25 mM stabilized aqueous solution
- 25 mM stock, pH=8.0
- 5 mM in H2O, pH=7.0
- 5 mM in HHBS, pH=7.0
