[Drosophila] Protein Extract from Larvae

[Kathleen Gajewski]

Ivy, Have you tried freeze-drying?  I've done Westerns, 2D gels and RNA 
preps from freeze tried tissues with good results.  Here's the 
reference:

Fujita S.C., Inoue H., Yoshioka T., Hotta Y., 1987.  Quantitative 
tissue isolation from Drosophila freeze-dried in acetone.  Biochem. J. 
243, 97-104.


Good luck,

KG
