[Histonet] Re. Not Too Sharpie !

[John Robertson]

Thanks to you ( and others) Gayle  for your timely alert,

I only used "Sharpie" as a shorthand for pen marking - I know well that 
standard Sharpie brand markers don't survive  processing. FYI --The 
markings shown in the referenced picture survive all processing .

Caveat:  True Sharpie marker, per se, ink is washed off by processing
solvents.  Are you refering to the STATMARK PEN (StatLab) or Superfrost
Marker II pen that LOOK like "sharpie" markers but have special ink that
stays on plastic cassettes?
