Qiagen s High-Performance Purity Grade Custom siRNAs

Premium

Qiagen has recently introduced high-performance purity grade custom siRNAs with a range of fluorescent labels and modifications, including Alexa Fluor dyes.

According to the company, custom siRNAs are available labeled with Alexa Fluor 488, Alexa Fluor 546, Alexa Fluor 555, or Alexa Fluor 647. Alexa Fluor dyes are more photostable and much brighter than traditionally used fluorescent dyes, Qiagen said.

The custom siRNAs can also come with special modifications on request, said Qiagen.

Additional information about the siRNAs can be found at http://www1.qiagen.com/Products/GeneSilencing/CustomSiRna/CustomSiRna.aspx.
