Mass fractionation of Drosophila egg chambers

Marcelo Jacobs-Lorena, Marco Crippa

Research output: Contribution to journalArticlepeer-review


Egg chambers from Drosophila ovaries may now be fractionated in large quantities suitable for biochemical work. A suspension of isolated egg chambers is prepared by subjecting ovaries to digestion with 0.067% collagenase. Egg chambers are separated in size classes (which correspond to different developmental stages) by sieving them through a column of superimposed nylon nets. The method can, in principle, be used for the separation of any particles ranging upward from 10 μm in diameter.
