Sequence analysis sample
preparation
• Prepare sequencing reactions according to kit instructions, and purify the
extension products with ethanol precipitation, spin columns, or the BigDye
XTerminator
™
Purification Kit.
– If ethanol precipitation or spin columns are used, dry the samples in a
vacuum centrifuge without heat or at low heat for 10–15 minutes or until dry.
Note: Do not over dry the samples.
– Resuspend in 10–20 µL of Hi‑Di
™
Formamide.
• Use a 65 µL or 130 µL sample volume for samples that are prepared with the
BigDye XTerminator
™
Purification Kit. See
BigDye XTerminator
™
Purification Kit
Protocol
(Pub. No. 4374408).
IMPORTANT! Use the appropriate run modules for samples prepared with
BigDye XTerminator
™
Purification Kit.
• Use a 10–20 µL sample volume for samples that are prepared with Hi‑Di
™
Formamide.
• Ensure that Hi‑Di
™
Formamide is fresh.
– Hi‑Di
™
Formamide should not undergo more than two freeze-thaw cycles (one
to aliquot and one for use).
– Use the same day after thawing.
• Do not resuspend samples in water, which can decrease sample stability.
