Abstract

ONT Rapid sequencing kit use in a classroom setting.

Steps

Library Preparation

1.

DNA tagmentation

Thaw kit components at Room temperature , spin down briefly using a microfuge and mix by pipetting as indicated below:

  • Lambda DNA (50 μg/ml): thaw at RT, briefly spin down, mix well by pipetting
  • Fragmentation Mix (FRA): not frozen, briefly spin down, mix well by pipetting
  • Rapid Adapter (RAP): not frozen, briefly spin down, mix well by pipetting
  • Sequencing Buffer (SQB): thaw at RT, briefly spin down, mix well by pipetting*
  • Loading Beads (LB): thaw at RT, briefly spin down, mix by pipetting or vortexing immediately before use
  • Sequencing Tether (SQT): thaw at RT, briefly spin down, mix well by pipetting
2.

Prepare the DNA in Nuclease-free water

2.1.

Transfer ~200ng genomic DNA into a 1.5 ml Eppendorf DNA LoBind tube

2.2.

Adjust the volume to 3.75µL with Nuclease-free water

2.3.

Mix by flicking the tube to avoid unwanted shearing

2.4.

Spin down briefly in a microfuge

2.5.

In a 0.2 ml thin-walled PCR tube, mix the following:

3.75µL 200 ng template DNA

1.25µL FRA

2.6.

Mix gently by flicking the tube, and spin down.

2.7.

Incubate the tube at 30°C for 0h 1m 0s and then at80°C for 0h 1m 0s . Briefly put the tube on ice to cool it down.
