Description

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
