Qiagen: Jan 31, 2008

Qiagen this week announced the release of the Allstars Hs Cell Death Control siRNA, which targets ubiquitous human cell survival genes.
“Transfection of this siRNA blend results in a high degree of cell death which is visible by light microscopy,” the company said. The siRNA can be ordered in tubes in 1-nmol, 5-nmol, or 20-nmol amounts, or in 96-well plates in 1-nmol, 0.25-nmol, or 0.1-nmol amounts.
The company also released the FlexiPlate siRNA Gene Family Lists, which are siRNA sets that enable RNAi screening of 54 human gene families. 
Controls, scales, and plate layout can be chosen to suit individual requirements, the company noted.
Lastly, Qiagen has launched the Whole Human Genome siRNA set v4, the Human Druggable Genome siRNA set v4, and subsets for GPCRs, phosphatases, and kinases.
The sets are provided in various scales and formats, including individual or pooled siRNAs.
The Human Whole Genome siRNA set targets 19,121 human genes, and can be supplemented with a set targeting 5,318 predicted additional genes. The Human Druggable Genome siRNA set targets 6,961 genes of potential therapeutic value, which the subsets target 490 GPCR genes, 696 kinase genes, or 205 phosphatase genes.
