Note:
·
It is not necessary to resuspend the magnetic beads completely—it is only
necessary to dislodge most of the beads that may be trapped in the keyhole.
The instrument resuspends the beads during the run when needed.
·
Fine bubbles can form above the liquid in some tubes after inversion. These
bubbles do not affect the run.
5.
Inspect all strips for large bubbles lodged under the surface of the liquid in the
tubes. Gently tap the strips on a benchtop to dislodge any bubbles without
splashing the contents onto the upper tube walls. If tapping fails to dislodge a
bubble, use the technique that is described in substep 4b until large bubbles are
dislodged.

Primer Pool Tubes must be manually filled
with the custom Ion AmpliSeq

or Ion AmpliSeq
™
HD panels at the appropriate
volume and in the correct primer pool tube positions. For Ion AmpliSeq

library
panels, use one carrier per DNA or RNA primer pool. The two positions in the primer
pool tube carrier are designated as shown in the following figure:
