3M Sodium acetate, pH 5.2 5.4 is supplied by HiMedia. It is available in the form of a colourless solution with a pH in the range of 5.2 to 5.4. Sodium acetate is a widely used reagent in molecular biology applications. It is used as a buffer in conjunction with acetic acid, in the buffering range of pH 3.6 - 5.6. 3M Sodium acetate solution is useful for DNA purification and storage and is routinely used in DNA and RNA precipitation. It is advisable to store this product at room temperature (15-25C).

Sodium acetate is the conjugate base of acetic acid, which is a weak acid. A solution of sodium acetate and acetic acid acts as a buffer to keep a relatively constant pH. The useful buffering range is pH 3.65.6. It has many biochemical applications where reactions are pH dependent. 3M Sodium acetate is commonly used in nucleic acid precipitation, protein crystallization, protein gel staining and in HPLC. This solution is mainly used for nucleic acid precipitation.
