A Simple and Quick Method to Isolate Nuclear Extracts from Pupae of Drosophila melanogaster.

Preparation of nuclear extracts is a critical step for biochemical identification of factors which function in the nuclei such as transcription factors. We have established a new method to prepare nuclear extracts from prepupae or pupae of Drosophila melanogaster. The method is simple and particularly useful for small-scale isolation from materials that are hard to get in large amounts such as specific tissues or animal bodies covered by pupal cases.
