A few years back there was a note in BioTechniques about the use of a cheap
alternative to these $$$$ products.  The product suggested was a childs paint
set, consisting of tubes of different colored fluorescent paint, that cost only
a few $ (for four).  The product is called "Neon Nightlites" and it is made by
Tulip Productions, Waltham MA 02254.  I bought a set at my local
stationery/bookstore, and I've been using them for the last 2 years.  The paint
is quite viscous, and takes a while to dry, so I usually label up some sticky
labels and put these on the wrapped membrane.  Works fine...

Cheers,

Martin
