Hi Mark
	We are using ImmEdge pens from Vector which I am assured by all who
use them are good in the wet

	See you

Dear all (esp in the UK),

I am interested in other peoples' methods of "ringing" sections for
immunocytochemistry.  Since the demise of the Dako PAP pens, we are
experiencing problems with other such pens, particularly when the nibs
get wet (NB: the slides in question are frozen sections stored at -70oC
and are difficult to mark).  Any info or remarks would be gladly
received.

Mark
