injection of an. stephensi embryos to generate malaria-resistant mosquitoes

<p class="jove_content">L&#39;introduzione di geni esogeni nel genoma delle zanzare richiede tecniche di microiniezione su misura per le specie di interesse specifico. Questo protocollo video dimostra un metodo utilizzato dal laboratorio di James a microinject costrutti di DNA in embrioni Anopheles stephensi per la generazione di zanzare trasformato. Tecniche di preparazione aghi microiniezione, la raccolta e la preparazione degli embrioni e l&#39;esecuzione della microiniezione sono illustrati.</p>

Injection of An. stephensi Embryos to Generate Malaria-resistant Mosquitoes

<p class="jove_content">Zanzare anofele stephensi sono vettori per la malaria che abitano l&#39;India e tutta l&#39;Asia. Questo video mostra la tecnica per l&#39;esecuzione di microiniezioni di questa specie con transgeni che conferiscono resistenza alla malaria alla zanzara. Gran parte della metodologia ha dimostrato in questo video è applicabile alle tecniche di microiniezione di altre specie di zanzare.</p>
