Plasmid DNA Elution Buffer is a Tris-buffered saline solution containing isopropanol, formulated for efficient plasmid DNA elution from purification column resins into solution. The optimized composition supports high DNA recovery while maintaining plasmid stability and integrity for downstream molecular biology applications. Tris provides stable buffering capacity, while the saline formulation ensures consistent elution performance. Isopropanol assists in releasing plasmid DNA from the column matrix, enabling efficient recovery with high purity and yield. Compatible with silica membrane and resin-based purification systems, this buffer is ideal for plasmid DNA purification workflows used in cloning, PCR, sequencing, and transfection applications.
