[Histonet] alternative to using pap pen?

[Eva Andersson]

Hi everyone,
I am going to be undertaking a large immunohistochemistry staining 
project. To ensure that our slides do not dry out during the primary 
antibody incubation we have decided to use pap pen. With such a large 
amount of slides this may be quite a task and so I would like to know if 
anyone has found a good alternative to the pap pen. The slides will 
arrive with the samples already on them.
Please let me know if you have any suggestions.
Thanks
