The purification procedure has been optimized to remove salts, enzymes, nucleotides, mineral oil, agarose, ethidium bromide and other impurities from DNA samples. Specialized binding buffers promote selective adsorption of DNA fragments and PCR products. The pure DNA is eluted in a small volume of buffer or water, ready to use for any subsequent application.
The MSB and Invisorb technology for purification of PCR products and DNA fragments is covered by patents and patent applications: DE10253 351.2 ,EP0765335B1, DE4422044A1, US6,037,465, EP1135479B1, DE19856064C2, DE19856064A1, EP01964906.0, DE10041825 A1, US5,141,719, DE10233790A1.
