Sigma-Aldrich, Qiagen, University of Tokyo

Sigma-Aldrich said this week that it has expanded its shRNA gene family sets in lentiviral format to include the Mission TRC shRNA human kinase gene family.

Qiagen has recently introduced the miRNeasy kits, a line of kits that enable purification of total RNA, including miRNA, or enrichment of miRNA and other small RNAs in a separate fraction.
The miRNeasy 96 kit is the first kit available for high-throughput purification in a 96-well format, the company said.
Qiagen also has launched RNA stabilization solutions, which allow samples to be stabilized, processed, stored, and transported at ambient temperature.

Researchers from the University of Tokyo recently launched siVirus, a web-based antiviral siRNA design tool.
The tool searches for functional, off-target minimized siRNAs targeting highly conserved regions of divergent viral sequences, according to the researchers.
The siVirus tool can be found at, and currently covers HIV-1, hepatitis C, SARS, and influenza.
