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

Northern Blot with IR Fluorescent Probes: Strategies for Probe Preparation.

Christopher Fields et al.

Bio-protocol, 9(8) (2019-08-21)

Northern blot is a molecular biology technique that can detect, quantify, and determine the molecular weight of RNA. Recently, we published a protocol utilizing near-infrared (IR) fluorescent probes in Northern blot (irNorthern). Our method is as sensitive as other non-radioactive

Isolation of DNA from bacterial samples of the human gastrointestinal tract.

Erwin G Zoetendal et al.

Nature protocols, 1(2), 870-873 (2007-04-05)

The human gastrointestinal (GI) tract contains a complex microbial community that develops in time and space. The most widely used approaches to study microbial diversity and activity are all based on the analysis of nucleic acids, DNA, rRNA and mRNA.
