Quote of of the summer, at this point? It's been a while!
My hypodermic syringe is of the simplest. It consists of a little glass tube, tapering sharply at one end. By drawing in my breath, I fill it with the liquid to be tested; I expel the contents by blowing. Its point is almost as fine as a hair and enables me to regulate the dose to the degree which I want. A cubic millimetre is the usual charge. The injection has to be made at parts that are generally covered with horn. So as not to break the point of my fragile instrument, I prepare the way with a needle, with which I prick the victim at the spot required. I insert the tip of the loaded injector in the hole thus made and I blow. The thing is done in a moment, very neatly and in an orthodox fashion, favourable to delicate experiments. I am delighted with my modest apparatus.

What's on my desk today? A reprint kindly sent by G. Goshima of the chapter:
Goshima (2010). Assessment of Mitotic Spindle Phenotypes in Drosophila S2 Cells. Methods in Cell Biol. Vol. 97.
Includes discussion of use of RNAi in S2 cells, appropriate controls, variability in the normal cell population, and mitotic mutant phenotypes.

Yan et al. (2010) A Genome-Wide Gene Function Prediction Resource for Drosophila melanogaster. PLoS One. 5(8). pii: e12139. Here's a link to the fly FuncBase website.
Of note: DRSC RNAi screen data sets were used in this study to help evaluate the predictions.

Also on my desk today? Like today's other post, a study in S2 cells that one could easily imagine leading to a high-throughput screen.

What's on my desk today?
A report describing the results of a microarray analysis of S2 cells treated with Juvenile Hormone. Several genes up- or down-regulated under these conditions were identified.
Willis et al. (2010) Microarray Analysis of Juvenile Hormone Response in Drosophila melanogaster S2 cells. J Insect Sci. 2010 Jun;10:66. PMID: 2067298.
