<p class="jove_content"> RNAi-vermittelten Gen-Silencing in Mücken, bedarf der vorherigen Herstellung und Reinigung von spezifischen dsRNAs, dass das Gen von Interesse Ziel. Für dsRNA-Synthese, empfehlen wir die Ambion Megascript Kit, Verwendung eines T7-RNA-Polymerase-vermittelte <em>in vitro</em> Transkriptions-Reaktion macht. Für dsRNA Reinigung empfehlen wir die Qiagen RNeasy-Kit. Proben von dsRNA zu quantifizieren und angepasst werden, um 3 ug / ul in Wasser. Andere Materialien, die Sie benötigen sind: spitzen Pinzette, Objektträger a...

<p> Effizienz der Gen-Silencing ist sehr variabel und hängt von einer Reihe von Faktoren, einschließlich Transkript und Protein turn-over-Raten und dsRNA Aufnahme Effizienz von Zellen und Organen. Wir haben festgestellt, dass Schweigen so früh wie 1 Tag nach der Injektion beginnt und kann bis zu 6 Tage nach der Injektion andauern. Verwenden Sie Transkript und Protein Nachweismethoden wie quantitative PCR und Western-Blot zu Schweigen zu validieren. </p>
