Glacial Acetic Acid Molecular Weight Overview

Glacial acetic acid is essential in the preparation of agarose gels. Agarose, a polysaccharide derived from seaweed, is used to create a gel matrix that serves as a molecular sieve for separating nucleic acids. When preparing an agarose gel, the agarose powder is dissolved in a buffer solution, typically containing Tris-acetate-EDTA (TAE) or Tris-borate-EDTA (TBE). Glacial acetic acid acts as a buffer component to adjust the pH of the gel, ensuring optimal conditions for nucleic acid migration during electrophoresis.
