Beschreibung

Allgemeine Beschreibung

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.[1]

Anwendung

Sodium acetate has been used:

• in the isolation of DNA from bacterial samples of the human gastrointestinal tract[2]
• as a component of RNA elution buffer for the preparation of infrared (IR) fluorescent probes in northern blot technique[3]
• in the lysis buffer for cellular lysis to detect reversible oxidation of protein tyrosine phosphatases (PTPs) with the cysteinyl-labeling assay using IMR90 fibroblasts[4]
