Ellen,

I am using the CyTek AMS sampler for a Calibur cytometer. After some
initial technical problems (the device does not handle shipping well) we
had good experience with the AMS. It is faster than the BD version, much
easier to operate, costs less than half of the BD sampler and you can learn
it's operation in a half hour.

The disadvantage of the CyTek over the BD sampler is that CyTek had no
access to the CellQuest code. To circumvent that the system cleverly
operates the CQ acquisition control buttons through a script. Unfortunately
you only can specify the total threshold events to be collected. The more
popular way of collecting a certain number of events in a gate is not
possible with the CyTek AMS.

The carryover between wells can be minimized with only a few seconds of
backflash and rinse steps. My experience is that increasing the acquisition
delay (to allow the pervious sample to run though the sample line) is more
useful than prolonged wash times.

I would seriously consider the CyTek sampler. Since we work in the same
neighborhood you are welcome to bring a plate with samples to Biogen and
I'll demonstrate the CyTek machine for you. I (regrettably) have no
financial incentive to doing so and try to be objective in my opinion.

More sophisticated, faster and robust multiwell samplers are needed. Is
anyone listening?

Hi All

Has anyone yet used the 96 well format from BD FACScalibur.  How is it
working?  Is 96 well format available from anyone else?  Have not kept
track
of other conversations along this line.  Thanks
