Collect DNA fragment
1.
Resume
the run
and carefully observe as
the band of interest fully enters the
recovery well.
2.
Stop the gel and recover the sample with a
pipette. Avoid piercing the agarose.
Some residual DNA will remain visible in
the well due to migration into the agarose
at the bottom of the well.
3.
Proceed with downstream cloning
workflow. No additional gel-purification is
required.
4.
(
Optional
) Collect additional DNA bands in
the same sample from the recovery well by
adding more water to the recovery well
(see page 26).
5.
(
Optional
) Use the
Reverse E-Gel
protocol
if the band of interest passes the recovery
well (see page 20).
Guidelines for estimating run time
•
Refer to the E-Gel
™
1 Kb Plus Express DNA Ladder migration pattern table to estimate
target DNA run time to the reference line.
•
The run times indicated in the table are estimates. Monitor your gel in real time during
the run to ensure the sample does not pass the recovery well.
•
Identically sized bands in different wells may migrate differently.
•
DNA fragment size, amount, and salt content can affect migration rates.
