Optimisation des protocoles existants Hybridations in situ sur des disques de l&#39;aile des larves ont été réalisées avec succès en utilisant des disques à partir des papillons coenia Précis (Carroll et al, 1994;. Keys et al, 1999;. Weatherbee et al 1999).. Le protocole actuel a été adapté à partir d&#39;un protocole écrit détaillé disponible sur demande auprès du laboratoire Carroll pour colorations aile larvaire. Les changements que nous a fait servir à tenir compte des différences entre les tissus des larves et ...

in situ protocol for butterfly pupal wings using riboprobes

Nous présentons ici, en format vidéo, un protocole pour les hybridations in situ dans les ailes des pupes de l&#39;anynana papillon Bicyclus utilisant ribosondes. Hybridations in situ, un pilier de la biologie du développement, sont utiles pour étudier la répartition spatiale et temporelle de l&#39;expression des gènes dans le développement de tissus au niveau de la transcription. Si des anticorps qui ciblent les produits de protéine de transcription des gènes n&#39;ont pas encore été développée, et / ou il ya de multiples copies du gène d&#39;une protéine particulière dans le génome qui ne peuvent pas être différenciés en utilisant des anticorps disponibles, situs peut être utilisé à la place. Alors une technique in situ pour les disques ailes larvaires ont été offerts à la communauté papillon pour plusieurs années, le protocole actuel a été optimisé pour les ailes plus grandes et plus fragiles chrysalide.
