Purification of α-amylase from Bacillus licheniformis by chromatofocusing and gel filtration chromatography.

A combination of chromatofocusing and gel filtration chromatography resulted in a simple purification of α-amylase from Bacillus licheniformis. The purification was approximately 77-fold. Identification of the purity was established by SDS–PAGE. Molecular weight and isoelectric point of the purified enzyme were 58 kDa and 7.18 respectively. Western blot analysis confirms the specificity of antibody raised against purified α-amylase. [ABSTRACT FROM AUTHOR]
