Just a quick query from a new flow-er (we've just purchased a FACS Calibur
after months of deliberating!! PS: thanks for all of the replies that I
received a while back with regards to B-D vs Coulter)...
I've been staining cells with BrdU & getting about 60-80% incorporation
after a 2h pulse - is this the norm? The cycling time of these cells is 12
h. I've tried adding PI to look at DNA content & find that 48% of the cells
are in S phase. Do these results make sense? I'm not a DNA person so I'm
not quite sure. Someone that I spoke to thought that it would make sense,
but my supervisor doesn't think so. So, I thought I'd ask the opinion of
people who do this everyday!
Also, if anyone could tell me how to make up the PI for DNA content studies,
I'd be much appreciative. It seems that people just use their stock (5x)
which is diluted in Triton X-100 forever!
Any help would be appreciated.
Thanks in advance,
