Buffer A1

Buffer A1 is a proprietary lysis and resuspension buffer formulated for efficient and gentle disruption of bacterial cells, enabling rapid release of plasmid or genomic DNA while maintaining nucleic acid integrity. It typically contains Tris-HCl (pH 8.0), EDTA, and RNase A to protect DNA from degradation and chelate divalent cations that destabilize cell membranes. Buffer A1 is optimized for use in plasmid isolation kits and nucleic acid purification workflows, providing consistent performance across different bacterial strains and culture conditions. It ensures high-yield, high-purity DNA recovery suitable for downstream molecular biology applications such as PCR, cloning, sequencing, and restriction analysis.
