<p class="jove_content">Optimization of existing protocols</p>

<p class="jove_content">In situ hybridizations on larval wing discs have been successfully performed using discs from Precis coenia butterflies (Carroll et al. 1994; Keys et al. 1999; Weatherbee et al. 1999). The current protocol has been adapted from a detailed written protocol available upon request from the Carroll Lab for larval wing stainings. The changes we made serve to accommodate differences between larval and pupal wing tissues.  During pupal hindwing dissections, the p...

in situ protocol for butterfly pupal wings using riboprobes

Here we present, in video format, a protocol for in situ hybridizations in pupal wings of the butterfly Bicyclus anynana using riboprobes.  In situ hybridizations, a mainstay of developmental biology, are useful to study the spatial and temporal patterns of gene expression in developing tissues at the level of transcription. If antibodies that target the protein products of gene transcription have not yet been developed, and/or there are multiple gene copies of a particular protein in the genome that cannot be differentiated using available antibodies, in situs can be used instead. While an in situ technique for larval wing discs has been available to the butterfly community for several years, the current protocol has been optimized for the larger and more fragile pupal wings.

Afin d'examiner l'expression des gènes dans les tissus des pupes de l'aile Bicyclus anynana, nous présentons un protocole optimisé pour les hybridations in situ en utilisant des ribosondes. Nous fournissons aussi des directives pour l'optimisation de ce protocole pour l'utilisation dans les ailes des pupes de espèces de lépidoptères autres.
