Large scale preparation of the mammalian high mobility group protein A2 for biophysical studies

Due to asymmetrical charge distribution of the mammalian high mobility group protein A2 (HMGA2), which makes HMGA2 bind to both cation- and anion-exchange columns, we developed a rapid procedure for purifying HMGA2 in the milligram range. This purification procedure greatly facilitated biophysical studies, which require large amounts of the protein.
