Problem
Possible cause and actions
Magnetic particles remaining
in the lysed sample or elution well
Starting material that is too viscose prevents efficient collection of
the KingFisher Magnetic Beads from the lysed sample. The magnetic
rods will not be able to collect all the magnetic beads unless the
viscose samples are diluted before the beginning of the purification
process. The samples can, for example, be diluted into 1 x PBS.
Improper lysis may also cause problems collecting the KingFisher
Magnetic Beads.
If the KingFisher Magnetic Beads are inefficiently collected from
the Elution Buffer, you should add a small amount of detergent
(e.g., 0.02% Tween 20) to improve the results.
Carryover of the KingFisher Magnetic Beads to the Elution Buffer
may affect the A
260
/A
280
ratio. Refer to
"Low purity"
on
page 35
.
KingFisher Magnetic Beads that occasionally remain attached to the
tip combs at the end of the process do not affect the DNA yield, as
the DNA has already been released from the KingFisher Magnetic
Beads into the Elution Buffer.
If the KingFisher magnetic particle processor does not work properly,
refer to the relevant user manual of the KingFisher instrument in use.
