General description

Sodium acetate is commonly applicable in molecular biology experiments such as nucleic acid purification and precipitation, protein gel electrophoresis, protein crystallization, and high-performance liquid chromatography (HPLC). Sodium acetate is also used in plastic production, dyeing, and leather tanning.

Application

Sodium acetate has been used:
  • in the isolation of DNA from bacterial samples of the human gastrointestinal tract
  • as a component of RNA elution buffer for the preparation of infrared (IR) fluorescent probes in northern blot technique
  • in the lysis buffer for cellular lysis to detect reversible oxidation of protein tyrosine phosphatases (PTPs) with the cysteinyl-labeling assay using IMR90 fibroblasts
