  1. aThis kit can be automated on the Qiagen QIAcube robotic workstation.
  2. bThis kit can be used manually.
  3. cFor the Plus Mini, Plus Universal and Maxwell® kits, an elution volume of 30 μL was used for RNA extracted from blood, embryos and larvae, while an elution volume of 50 μL was used for RNA isolated from spleens and kidneys. Elution volumes for all tissues extracted via the MagMAX™ and SimplyRNA HT kits were 55 and 50 μL, respectively.
  4. dList price in June 2013; Prices are for the kits only and do not include the costs of equipment and reagents not supplied with the kit.
  5. eBeta test kit of a new 96-well format high throughput, RNA purification system. Final specifications in development.
