Novel Assay: Detecting JH

This paper describes an improved approach to detecting farnesoic acid and juvenile hormone. A starting point for a large-scale in vivo RNAi screen perhaps? Open access paper.

Breaking Report: dsRNA Uptake

Also on my desk to read today?  This paper, which includes a description of what happens following introduction of C. elegans SID-2 into Drosophila S2 cells.

Breaking Report: F-Box Protein in vivo RNAi Study

On my desk to read today? An in vivo study in which the researchers systematically tested the effects of knockdown of genes encoding F-box-containing proteins.

Breaking Report: Plasmid Toolset for in vivo Expression or RNAi

On my desk to read today? A report of a set of plasmid vectors useful for in vivo expression of various forms of tagged or untagged genes or RNAi constructs.

Wang JW, Beck ES, McCabe BD. A modular toolset for recombination transgenesis and neurogenetic analysis of Drosophila. PLoS One. 2012;7(7):e42102. Epub 2012 Jul 25. PubMed PMID: 22848718

The authors indicate that the plasmids are available at AddGene.
