Abstract
A cost-efficient protocol for constructing a Flongle library.
Materials
PEG/NaCl precipitation buffer (see Rocky Mountain adventure protocol)

AB
PEG 80009% (w/v)
NaCl1 M
Tris-HCl (pH 8.0)10 mM

PEG wash buffer

Dilute PEG/NaCl precipitation buffer with the same amount of water.
Assemble the following components to end repair and add A to the genomic sample:

AB
Ultra II buffer1.75
End repair buffer1.75
Ultra II enzyme1
End repair enzyme1
DNAx (500 ng)
MQ44.5 - x
Incubate at 20 °C for 00:05:00 , then 65 °C for 00:05:00 .



10m
Add 50 µL of Ampure beads (or equivalent beads) and mix well.
Wash with 75 % EtOH twice and elute with 11 µL of 10 millimolar (mM) Tris-HCl (pH 8.0).
Keep the tube on the magnetic rack and do not disturb the beads while washing with 75% EtOH.
Use 1 µL of the solution to check the concentration with Qubit. The concentration needs to be at least 30 ng/uL .
Assemble the following components for ligation:

AB
DNA10 uL
TLB4 uL
Quick ligase1.5 uL
AMX0.8 uL
Incubate at Room temperature for 00:30:00 .
Add 2.3 µL of 5 Molarity (M) NaCl and incubate at Room temperature for 00:30:00 and then cfg at max speed for 00:20:00 .
Remove sup and add PEG wash buffer, cfg at max speed for 00:01:00 .
Remove sup and add 11 µL of 10mM Tris-HCl (pH 8.0) and incubate at 4 °C forOvernight .
Check the concentration with Qubit.

1h 21m
Assemble the following priming solution:

AB
FLB2.5 uL
FB97.5 uL
and the library mix solution:

AB
DNAx uL (100 ng)
SB II10 uL
LB II4 uL
MQ6 - x uL
. Load them and start sequencing.
