Se presenta una técnica para el etiquetado de las neuronas individuales en el sistema nervioso central (SNC) de

El objetivo general de este procedimiento es etiquetar neuronas individuales en el sistema nervioso central de embriones de Drosophila en etapa temprana 17. Esto se logra recolectando huevos y permitiendo que se desarrollen hasta la etapa correcta. El segundo paso del procedimiento es clorar y alinear manualmente los huevos.

Después de esta diva, la colonización y filetación de los embriones hace que el cordón nervioso sea accesible. El paso final es etiquetar las células individuales mediante la aplicación de Iono retic del ojo de matriz lipofílica. En última instancia, los resultados permiten la visualización de la morfología de una sola neurona si se desea en el contexto de patrones de expresión de GFP conocidos y/o en un fondo mutante.
