Qiagen s Human/Mouse Control Kits, Ambion s Silencer and Gene Ontology Database, and Genetic Engineering News and Assay and Drug Development Technologies Online Seminar


Qiagen recently released its RNAi human/mouse control kits.

According to the company, the kits include a complete set of controls to optimize RNAi in both human and mouse cells, RNAiFect transfection reagents, and Alexa Flour 488 labeled non-silencing siRNAs to monitor transfection.

Ambion has recently introduced two new Silencer siRNA libraries.

The first contains siRNAs to 51 human nuclear hormone receptors, and includes three siRNAs per target. According to the company, the nuclear hormone receptor targets were chosen based on their inclusion in the Gene Ontology database.

The second library contains siRNAs to 38 human caspase and caspase-related targets, and includes three siRNAs per target. Again, the targets were selected based on their inclusion in the Gene Ontology database, said Ambion.

Details about the libraries can be found at, and, respectively.

Genetic Engineering News and Assay and Drug Development Technologies are sponsoring an online seminar entitled “High-Throughput, High-Content RNAi Assays.”

The event is scheduled to occur on May 5 at 12 noon, Eastern time, and will feature Christophe Echeverri, CEO and CSO of Cenix Bioscience, and David Dorris, director of RNAi technologies at Ambion.

Details about the one-and-a-half hour presentation, which will cover such topics as strategies for gaining meaningful information from RNAi assays and pitfalls to avoid in RNAi-based screening experiments, can be found at
