Step 3. Repair the ends
Use the SureSelect XT Library Prep Kit ILM for this step.
To process multiple samples, prepare master mixes with overage at each
step, without the DNA sample. Master mixes for preparation of 16 samples
(including excess) are shown in each table as an example.
Hold samples on ice while setting up this step.
1 Prepare the appropriate volume of End Repair master mix, as described
in Table 21, on ice. Mix well on a vortex mixer.
Table 21 Preparation of End Repair master mix
2 Add 52 µL of the master mix to each PCR plate well containing the
sheared DNA samples (approximately 48–50 µL). Mix by pipetting up
and down.
3 Incubate the plate in the thermal cycler and run the program in
Table 22. Do not use a heated lid.
