Problem
Cause
Solution
Low DNA yield.
Insufficient
amount
of
magnetic beads added.
During
shipping,
some
magnetic bead solution may
adhere to the sealing foil of the
cartridge. To collect any bead
solution from the foil, tap the
cartridge to deposit the bead
solution at the bottom of the
well.
Clogged Tips, resulting in DNA
loss.
Ensure that the lysate does not
contain
any
particulate
material that can clog the tip. If
needed, centrifuge the sample
prior to the extraction process.
No DNA recovered.
Magnetic beads stored or
handled improperly.
Store cartridge containing the
beads at room temperature.
Do not freeze the cartridge, as
the beads may be irreparably
damaged.
Make sure that the beads are
in solution at all times and do
not dry. Dried beads are non-
functional.
Eluate containing DNA
is discolored.
Magnetic beads present in the
eluate.
Remove any magnetic beads
using a magnetic separator, or
centrifuge the sample in a
microcentrifuge for 1 minute
at maximum speed.
