Nuclear and Cytoplasmic Soluble Proteins Extraction from a Small Quantity of Drosophila's Whole Larvae and Tissues

Int J Mol Sci. 2015 Jun 1;16(6):12360-7. doi: 10.3390/ijms160612360.


The identification and study of protein's function in several model organisms is carried out using both nuclear and cytoplasmic extracts. For a long time, Drosophila's embryos have represented the main source for protein extractions, although in the last year, the importance of collecting proteins extracts also from larval tissues has also been understood. Here we report a very simple protocol, improved by a previously developed method, to produce in a single extraction both highly stable nuclear and cytoplasmic protein extracts from a small quantity of whole Drosophila's larvae or tissues, suitable for biochemical analyses like co-immunoprecipitation.

Keywords: Drosophila; hnRNPs; proteins extraction.
