Lesli Armstrong makes a very good point in her message about PI. I wish you all the
best Leslie as you deal with this traumatic situation.

One thing that I have stressed over the years, is that when you are sorting with PI or
any fluorochrome for that matter, you could be exposing yourself to PI in the aerosol. I
think this is a very good reason to re-evaluate sorting procedures. Although we have
discussed this for years, it has encouraged me to go take another look at this issue.

Hi,
 Seeing these posts about safety precautions to be used while
pregnant and working in flow cytometry prompted me to send a word of
caution to ALL flow cytometrists, pregnant or not.  We all need to be
careful when using toxic, carcinogenic, pathologic, etc. samples or
chemicals.  We tend to get so used to working with this stuff, that I
think we forget to respect the potential hazards.
 I was diagnosed with thyroid cancer last year, and although the
only "known" cause of thyroid cancer is radiation exposure (which I
have not had), the nuclear medicine doctor that administered my
ablative dose of I131 following my surgery was curious about my
exposure to propidium iodide for 15 years.  Even though it is not
supposed to be taken up by live tissue,, he did wonder if it could
cause thyroid cancer, as the thyroid has such an affinity for iodine of
any sort.  I don't know if anyone would have any answers to this, but I
just wanted to make sure everyone, not just pregnant ladies, respects
the warnings to use caution when dealing with dyes, chemicals, body
fluids, etc.  Be safe out there!!
