HiMedia offer spin column based kits which provides fast and easy purification of total DNA/RNA for reliable applications in PCR, sequencing, cloning, blotting, restriction digestion, ligation and Southern blotting by the use of silica binding in a micro spin format that eliminates the need for expensive resins, alcohol precipitation and hazardous organic compounds such as phenol and chloroform. DNA/RNA binds specifically to the Silica-gel membrane while contaminants pass through. PCR inhibitors such as divalent cations and proteins are completely removed in two or more efficient wash steps, leaving pure nucleic acid to be eluted in either water or a buffer provided with the kit.
