DNA tagmentation
-
Thaw the kit components at room temperature, spin down briefly using a microfuge and mix by pipetting as indicated by the table below:
Reagent 1. Thaw at room temperature 2. Briefly spin down 3. Mix well by pipetting Fragmentation Mix (FRA) Not frozen ✓ ✓ Rapid Adapter (RA) Not frozen ✓ ✓ Adapter Buffer (ADB) Not frozen ✓ ✓ Lambda DNA (LMD) ✓ ✓ ✓ -
Once thawed, keep all the kit components on ice.
-
Prepare the Lambda DNA in nuclease-free water.
- Transfer 2 µl Lambda DNA into a 1.5 ml Eppendorf DNA LoBind tube
- Adjust the volume to 10 µl with nuclease-free water
- Mix by flicking the tube to avoid unwanted shearing
- Spin down briefly in a microfuge
-
In a 0.2 ml thin-walled PCR tube, mix the following:
Reagents Volume (µl) Lambda DNA 10 Fragmentation Mix (FRA) 1 Total 11 -
Mix gently by flicking the tube, and spin down.
-
Incubate the tube at 30°C for 2 minutes and then at 80°C for 2 minutes. Briefly put the tube on ice to cool it down.
-
The tagmented Lambda DNA in 11 μl is taken into the next step.
-
Adapter attachment
-
In a fresh 1.5 ml Eppendorf DNA LoBind tube, dilute the Rapid Adapter (RA) as follows and pipette mix:
Reagents Volume Rapid Adapter (RA) 1.5 μl Adapter Buffer (ADB) 3.5 μl Total 5 μl -
Add 1 μl of diluted Rapid Adapter (RA) to the tagmented DNA.
-
Mix gently by flicking the tube, and spin down.
-
Incubate the reaction for 5 minutes at room temperature.
