Starting up the system
During the work week the core will have the Aria ready
for use. You will need to log on, start the stream and
examine the breakoff image and values to confirm it is
ready.
Turn on the cytometer main power (switch on left side)
Turn on the computer if needed, log on with your
UMass ID
Open the “Coherent Connection” software
Open FACSDiva, log in with your unique password
which we will set up for you
Wait for FACSDiva to connect to the cytometer and
“Use CST settings” when the CST mismatch dialog
box appears
Start the stream*, one nozzle (85 µm) only will be used
for self-sorting in the core which is suitable for most
cell types. You should use the recorded drop breakoff
parameters (amplitude, frequency, drop 1 and gap)
which are written in the log book and are stored in
FACSDiva
You may need to adjust the amplitude to move drop 1
close to the recorded spot. Engage the “sweet spot”
Verify that the small satellite drops are merging with
the large drops.
The satellite drops should merge into the large drops
in 6 or fewer satellites.
NEVER run a sample which has NOT been filtered
through our 37 µm mesh or BD tubes # 352235
