Lost cells

Too true Alice,

Many's the time I've traipsed back to the the punters lab to find discarded
supernatant swimming with cells when they've been piqued at the "poor
recovery" by the sorter.  Most people seem to check what they put into a
centrifuge, but seldom what they get out, and they always seem to use the
most gentle spin cycle  to protect their cells (from hitting the bottom of
the tube).
