It depends what you are after.  There are specialised plates which
are surface treated to enhance binding of subsets of molecules
(eg. positively or negatively charged, biotinylated) but often a survey
of "normal" (and thus much cheaper) plates will reveal one that is
the best for you.  Back in London we checked out over half a dozen
different plates (tissue culture. microtitre, and some "high binding"
plates) and there was a huge variation in performance.  Our
particular winner was Dynatech's Immulon.  Some of the "increased
capacity" plates certainly gave high signals but with greatly
increased backgrounds.  If you *really* have to have high capacity
then I suggest you consider dot or slot blotting as an alternative
as this gives more quantitative loading (but is of course a real
pain if you have to run lots of samples).
     I hope you find a good 'un,
