RE: Slide markers
I just tried this new pen, a sample accessed at NSH convention, greatly
appreciated and thanks to the vendor!!
However, even with longer drying time than 30 - 45 seconds (they recommend
60 sec, did longer here) and after reading their lengthy explanation on how
to use the pen with all the variables (slides, etc, etc, etc - mine were
Plus Charge) I loved the way this pen didn't dry out
During the IHC procedure, black ink oozed (visibly!) into buffer over my
sections druing immunostaining of both 60C oven dried paraffin sections AND
acetone/alcohol fixed frozen sections using buffer/diluents with Tween 20.
Ho hum, worrisome black ink contamination over my immunostained sections
with potential?? interference of staining by the ink drove me back to
Secureline pens (or "See how fast they dry out this time Brand'!, Sorry!
breaking my own rule about bashing here). You could see black ink on
KIMWIPE after blotting buffer from edge of section and also watch it ooze
away from label end.
They are on the right track for pen improvement, but my pen is sidetracked
indefinitely until ------- After reading their instruction sheet, I might
gather they had seen similar problems with all their warnings/how to's/what
to use, etc. I hope they get 'ink ooze' problem corrected.
