Symptom

Possible Causes

Recommended Solutions

Event rate is

slower than

expected

Sample concentration

is low

Make sure the sample concentration is between 10

7

and 10

8

cells/ml. Lower

concentrations can be used but this will decrease the cells/second.

Core is off center

Cropped images will be eliminated from data acquisition and if enough of the

images are cropped the event rate can appear lower than normal. Normally
this is due to air in the system. Run the purge bubbles script from the instru-

ment drop-down menu.

For more information, see Unstable fluidics (Air or clog in

Insufficient illu-

mination

Turn the appropriate lasers on. Set the 785 SSC laser to 40mw. Set the laser

powers to maximum and decrease them to prevent pixel saturation.

Cross-con-

tamination from

previous

samples

DNA dye from pre-

vious sample is

labeling current

sample

DNA dyes must be thoroughly flushed from the sample lines, to prevent resid-

ual dye from labeling subsequent samples. Load a sample of 10% bleach fol-

lowed by a PBS wash, to remove all traces of the DNA dye in the instrument,

or run the sterilize script (~30min).

Cells from the pre-

vious sample are

appearing in current

sample

This suggests a minor clog. Load a sample of 10% bleach followed by a PBS

wash to remove most contaminating cells, or run the sterilize script

(~30min).

Erroneous fluid

level indicator

Tank has moved away

from the sensor

Open the buffer compartment and move the tank closer to the sensor until

the fluid level indicator is correct.

Sensor is broken

Power down and power up the instrument, if this does not fix the problem,

call Luminex Technical Support.
