First, if you want replies, you should probably change your e-mail address
to a valid one. Second, in your position I wouldn't bother trying to
pre-stain your markers; transfer to unstained markers and then stain your
NC with india ink, exactly as described in Harlowe's antibody manual
(from Cold Spring Harbor Press, I hear a new version is coming out
soon). The non-stained markers will almost certainly run more accurately
and tighter than do the prestained ones, and the time and effort in india
ink staining are trivial; you can also use much less marker.
There's really very little advantage to using prestained marker in
Westerns over the india ink staining.
