Sodium chloride solution 5 M
Sodium chloride (NaCl), common salt also known as halite, is ubiquitous in occurrence and has many vital applications. It is a white crystalline solid, fairly soluble in water. NaCl is a flavouring agent in the food industry and used for texturing bread and baked foods. NaCl is an essential salt for normal body functions in humans and animals.[1] NaCl is essential for maintaining plasma osmolality and extracellular fluid volume of the body. Excess of NaCl leads to elevated blood pressure which has implications on cardiovascular and renal diseases.[4] NaCl is a basic component in the microbiological medium, specifically for culturing of halophiles.[2] Sterile NaCl is a constituent of eye drop solutions.[3]
Sodium chloride has been used:
• as a supplement in serum free media for CA3 pyramidal neuron layer preparation[5]
• in the preparation of oligonucleotides (ODNs) annealing buffer[6]
• in
the preparation of phosphate buffered saline and in phosphatase methylesterase-1 (PME-1) inhibition and counterscreen assay buffers[7]
