Protocol
TagmentationTM Reaction
- 1. Prior to assembling the reaction, briefly centrifuge ALL tubes to assure that the reagents are at the bottom of the tubes.
- 2. Assemble the following reaction components on ice, in the order listed:
12.67ul Nuclease-Free Water 2.33ul 100ng NA12878 gDNA (42.9ng/ul) 4ul 5X Nextera HMW Reaction Buffer 1ul Nextera Methyl-Seq Tagmentation Mix (Illumina-compatible) 20ul Total reaction volume
- 3. Mix briefly by vortexing, and incubate at 55C for 5 minutes.
- 4. Purify the tagmented DNA using Qigen column and elute with 11ul Elute buffer
- 5. Add 10 μl of 2X Nextera Fill-in Buffer and 1 μl of Nextera Methyl-Seq Polymerase to 10 μl of the eluted/Tagmented DNA.
Mix and incubate at 70C for 10 minutes.
- 6. Purify the Fill-in reaction using a Qiagen column as in Step 4 above.
