KCl is a component of extracellular buffer for Ca2+ imaging in cells..
By Anonymous on 07/02/2019
Assay Type: In Vitro
Species: Human
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.

Species: Human

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