DNase Protocol

From OpenWetWare

Overview

Protocol for the Ambion DNA-free DNase kit. This uses a DNase inactivating reagent and thus avoids the DNase heat inactivation step that makes me nervous.

Materials

List reagents, supplies and equipment necessary to perform the protocol here. For those materials which have their own OWW pages, link to that page. Alternatively, links to the suppliers' page on that material are also appropriate.

• supply 1 (i.e. tubes of a certain size? spreaders?)
• reagent 1
• X μL reagent 2
  • component A (reagent 2 is made up of multiple components)
  • component B
• equipment 1
• equipment 2

Procedure

1. In order to DNase 20ug of RNA in a 100ul reaction, mixup the following:

• 10ul 10X DNase buffer
• 78ul dH₂0
• 2ul DNase
• 10ul *RNA(1ug/ul)

1. Incubate at 37° C for 20-30 min.

Notes

1. List troubleshooting tips here.
2. You can also link to FAQs/tips provided by other sources such as the manufacturer or other websites.
3. Anecdotal observations that might be of use to others can also be posted here.
