Microtitre plates: edge effects?

[Donald Chun Kit Wong]

A grad student in the lab has been using a commerical ELISA kit for 
detection of a secreted antigen she's interested in. But because of te 
high cost of these kits (>$500 per plate), she has decided to purchase 
separate reagents, antibodies, etc. and make her own plates. As a novice 
in this, I wonder if anyone has any advice, useful articles, books, etc. 
Thanks.
