Examples of potassium

• Cesium in the intracellular solution blocks potassium channels like delayed rectifier and inactivating potassium channels.

• These include a regenerative sodium current, the potassium inward rectifier, potassium delayed rectifier and transient outward potassium current, and several calcium currents.

• Starch grains were visualized by a weak solution of iodine (0.3 g iodine and 1.5 g potassium iodide in 100 ml water).

• Sustained and transient potassium currents of cultured horizontal cells isolated from white bass retina.

• The glomerular lesions and disappearance of glomeruli compromised the renal function of these animals, a fact reflected in raised serum potassium and urea concentrations.

• This observation suggests that the potassium present on the organic materials became easily available upon incorporation into the soil.

• Most notable is the high concentration of potassium in pseudostem and stalk.

• Samples of 10-50 g of coal were macerated in nitric acid and then cleared in potassium hydroxide.
