DNA-Aufreinigungs-Kondensator: BeschreibungDNA Purification Capacitor: Description
Ein bei molekularbiologischem Arbeiten häufig auftretender Arbeitsschritt besteht in der Isolierung, Separierung bzw. Aufreinigung von Desoxyribonucleinsäure (DNA). Dabei handelt es sich um einen relativ aufwendigen, schwer zu automatisierenden Arbeitsschritt. Üblicherweise wird die DNA entweder mittels Ethanol gefällt, mittels Phenol/Chloroform extrahiert, oder mittels Ionenaustauschersäulen gebunden und bei saurem pH eluiert. Bei dieser Erfindung steht nun die Überlegung im Vordergrund die DNA elektrostatisch an die Kunststoff- Wandung des verwendeten Reaktionsgefäßes zu binden, um sie anschließend durch Umpolen des Kondensators wieder freizusetzen. Ein derartiges Vorgehen vereinfacht molekularbiologisches arbeiten und ermöglicht die Automatisierung dieses essentiell wichtigen Arbeitsschritts. Am einfachsten lässt sich die elektrostatische DNA Aufreinigung mittels eines Plattenkondensators realisieren. In dessen elektrisches Feld wird das Reaktionsgefäß oder die 96 well Platte mittels entsprechender Bohrungen durch die obere Platte des Plattenkondensators eingebracht. Dabei wird nun die untere Platte, die dem Boden des Reaktionsgefäßes bzw. der 96 well Platte benachbart ist, positiv aufgeladen. Desoxyribonukleinsäure ist aufgrund des Phosphatdiester - Rückrads elektrisch negativ geladen. Aufgrund dieser Ladung wird die Desoxyribonukleinsäure von der Wandung des Reaktionsgefäßes in dem hier beschriebenen Apparat absorbiert. Diese Absorbtion lässt sich durch Aufrauung des Reaktionsgefäßes verbessern, da so die Oberfläche vergrößert wird. Eine weitere Möglichkeit die Absorbtions - Kapazität des Reaktionsgefäßes zu erhöhen, besteht darin Silikat Säulenmaterial bzw. Anionen-Austauschermaterial in das Reaktionsgefäß einzubringen. Nach Absorbtion der Desoxyribonukleinsäure an das Wandmaterial kann die DNA gewaschen und so, beispielsweise von Oligonukleotiden, Mononukleotiden, Didesoxynukleotiden, gereinigt werden. Im Anschluss daran kann die Desoxyribonukleinsäure durch Umpolung des Kondensators desorbiert und in den geeigneten Puffer freigesetzt werden.A frequently occurring step in molecular biology work is the isolation, separation or purification of deoxyribonucleic acid (DNA). This is a relatively complex step that is difficult to automate. Usually, the DNA is either precipitated using ethanol, extracted using phenol/chloroform, or bound using ion exchange columns and eluted at an acidic pH. The main idea behind this invention is to electrostatically bind the DNA to the plastic wall of the reaction vessel used in order to then release it again by reversing the polarity of the capacitor. Such a procedure simplifies molecular biology work and enables the automation of this essential step. The easiest way to carry out electrostatic DNA purification is using a plate capacitor. The reaction vessel or the 96-well plate is placed in the electric field of the plate capacitor using appropriate holes drilled through the upper plate of the plate capacitor. The lower plate, which is adjacent to the bottom of the reaction vessel or the 96-well plate, is then positively charged. Deoxyribonucleic acid is electrically negatively charged due to the phosphate diester backbone. Due to this charge, the deoxyribonucleic acid is absorbed by the wall of the reaction vessel in the apparatus described here. This absorption can be improved by roughening the reaction vessel, as this increases the surface area. Another way of increasing the absorption capacity of the reaction vessel is to introduce silicate column material or anion exchange material into the reaction vessel. After the deoxyribonucleic acid has been absorbed by the wall material, the DNA can be washed and thus purified, for example, from oligonucleotides, mononucleotides, dideoxynucleotides. The deoxyribonucleic acid can then be desorbed by reversing the polarity of the capacitor and released into the appropriate buffer.
