Optimización de los protocolos existentes Hibridaciones in situ en los discos de ala larvas se han realizado exitosamente usando discos de Precis mariposas coenia (Carroll et al 1994;. Keys et al 1999;. Weatherbee et al 1999).. El actual protocolo ha sido adaptado de un protocolo escrito detallado disponible a petición del Laboratorio de Carroll para tinciones alas larvas. Los cambios que hemos hecho servir para dar cabida a las diferencias entre los tejidos del ala de larva y pupa. Durante pupal disecciones alas posteriores, la m...

in situ protocol for butterfly pupal wings using riboprobes

Aquí presentamos, en formato de vídeo, un protocolo para hibridaciones in situ en las alas de la crisálida de mariposa anynana Bicyclus con riboprobes. Hibridaciones in situ, uno de los pilares de la biología del desarrollo, son útiles para estudiar los patrones espaciales y temporales de la expresión génica en el desarrollo de los tejidos a nivel de la transcripción. Si los anticuerpos que se dirigen los productos de proteína de la transcripción de genes todavía no se han desarrollado, y / o hay varias copias del gen de una proteína en el genoma que no se puede diferenciar el uso de anticuerpos disponibles, en situs se puede utilizar en su lugar. Mientras que una técnica in situ para los discos de ala larval ha estado disponible para la comunidad de mariposas durante varios años, el actual protocolo ha sido optimizado para las alas más grandes y más frágiles de pupa.
