Il 2-colore montare tutto nel metodo di ibridazione in situ è ​​utilizzato per determinare sia i modelli spaziali e temporali di espressione genica, utilizzando uno o due geni di interesse. Le applicazioni includono la valutazione dei pattern di espressione genica di nuovi geni (ad esempio 1,2, così come i cambiamenti nel gene insulto seguente espressione (manipolazione embrionale 3, perline 4, ed elettroporazione di RNA o DNA costruisce 5).

double whole mount in situ hybridization of early chick embryos

L&#39;embrione di pollo è uno strumento prezioso per lo studio dello sviluppo embrionale precoce. La sua trasparenza, accessibilità e facilità di manipolazione, lo rendono uno strumento ideale per studiare l&#39;espressione genica nel cervello, del tubo neurale, somite e il cuore la formazione di primordi. Questo video mostra le varie fasi a 2 colori montare tutto ibridazione in situ; In primo luogo, l&#39;embrione è sezionato dall&#39;uovo e fissati in paraformaldeide. In secondo luogo, l&#39;embrione è trasformato per prehybridization. L&#39;embrione viene quindi ibridato con due sonde diverse, una accoppiata a scavare, e uno accoppiato al FITC. A seguito di ibridazione durante la notte, l&#39;embrione viene incubato con l&#39;anticorpo DIG accoppiati. Reazione del colore per substrato DIG viene eseguita, e la regione di interesse appare blu. L&#39;embrione viene quindi incubato con anticorpo FITC accoppiati. L&#39;embrione è trasformato per una reazione a colori con FITC, e la regione di interesse appare rosso. Infine, l&#39;embrione è fisso e trattati per phtograph e sezionamento. Una guida alla risoluzione è anche presentato.
