[Drosophila] Protocols and methods to homogenize flies

[Andre Faustino]

Dear all,

=20

I am trying to quantify proteins, sugars and lipids in flies but having tro=
uble with the homogenization step.

So far I am homogenizing flies with a motor pestle in PBS. Then I perform a=
 series of spins to remove tissue.

I use the supernatant to conduct the tests, but I am having troubles in get=
ting sufficient amount of material, especially to conduct the tests to eval=
uate lipid content of my samples. This leads to problems in sample comparis=
on since different levels of homogenization lead to different results obtai=
ned.

Can someone please provide me with protocols and tips for homogenization of=
 whole flies?

Thanks,
