commercially available miRNA or small RNA? - (Jul/07/2014 )

I'm looking to purchase some commercially available microRNA or small RNA, but I can't seem to locate anything. I was wondering if anyone knew of some options besides isolating it myself.

Thanks

A number of companies will produce siRNA/miRNA for you if you submit a sequence.  Many of them have designers on their webpages too.  Invitrogen's stealth siRNA used to be quite good when I last used them.

Update- Preferably I wanted to use miRNA isolated from animal tissue (non-synthetic). I was considering isolating it myself using a specialized kit, but was able to find some pre-isolated miRNA offered by Zyagen (http://zyagen.com/index.php?main_page=index&cPath=4_94).
