Creative Diagnostics provides beads based DNA Extraction and Purification Kits for rapid and reliable isolation of DNA, including genomic DNA, plasmid DNA and viral DNA. Unique coated magnetic beads are designed to bind DNA with high affinity. After magnetic separation and elution steps, high-quality DNA can be obtained with high yield and purity, which is suitable for following biological applications, such as enzyme digestion, sequencing and analysis. This is a far less rigorous method than traditional DNA separation techniques, which involves precipitation and centrifugation steps that may lead to the degradation of the nucleic acids. Magnetic beads based DNA extraction and purification allows isolation of high-quality DNA from various samples, including cell supernatant, serum, urine, ascites and other body fluids.
