Description générale

Potassium is an intracellular cation with just 2% of total body K+ inhabiting the extracellular fluid. The distribution of K+ between the intracellular and extracellular space is analyzed by the action of several transport pathways like Na+-K+-ATPase, the Na+-K+-2Cl-cotransporter NKCC1, the four KCCs, and a plethora of K+ channels. Also, skeletal muscle comprises almost 75% of total body potassium and elicits considerable influence on extracellular K+. Potassium chloride is consumed orally to prevent or correct potassium depletion caused by diuretic use or other conditions. It is used as a food supplement and salt substitute.

Application

Potassium chloride solution has been used as a component of:
  • multiple annealing and looping based amplification cycles (MALBAC) lysis buffer to digest proteins for single-cell multiomics sequencing
  • single-cell tagged reverse transcription (STRT) buffer, and STRT-RT buffer for single-cell RNA-sequencing
  • phosphate buffer saline (PBS) to wash transfected cells

Bacterial nucleoid-associated proteins, such as H-NS-like proteins in Enterobacteriaceae, are abundant DNA-binding proteins that function in chromosomal DNA organization and gene transcription regulation. The Mycobacterium tuberculosis Lsr2 protein has been proposed to be the first identified H-NS analogue in Gram-positive

High-protein diets induce alterations in metabolism that may prevent diet-induced obesity. However, little is known as to whether different protein sources consumed at normal levels may affect diet-induced obesity and associated co-morbidities.
