WANTED: Marking Pen for Autorads

hello All,

Can anyone suggest a marking pen to mark blots?  I'm looking for a 
luminescent-type pen which will 'burn' a mark into the autorad so it can 
be aligned with a blot or lift.  In the past I have used labeled ink 
(35S) but we no longer use this isotope regularly plus its not very safe 
(although it does work prety well).  I have also tried lumninesent nail 
polish but this sticks to the autorads which is pretty messy.  I have 
seen some rediculously expensive 'stickers' marketed by Stratagene and 
Sigma, haven't tried them because of price.

Any suggestions for 'home grown' markers or a commercailly available marker?

Thanks in advance,

Paul Bucciaglia
