Preparing Stock Solutions for Potassium chloride

The following data is based on the product molecular weight 74.55. Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
20 mM 0.67 mL 3.35 mL 6.71 mL
100 mM 0.13 mL 0.67 mL 1.34 mL
200 mM 0.07 mL 0.34 mL 0.67 mL
1000 mM 0.01 mL 0.07 mL 0.13 mL

Cell Line/Tissue: HEK293

KCl (5.4 mM) is added in the extracellular buffer, consisting of (in mM) 137 NaCl, 1 CaCl2, 1 MgCl2, 10 HEPES and 10 glucose and pH is adjusted to 7.4 with NaOH and used to perfuse cells during Ca2+ imaging in Fura2-loaded cells.

KCl used to make potassium buffer for cell loading.

I have used KCl for loading my cells with potassium prior to potassium efflux studies. Potassium chloride was used to make potassium buffer.
