An alternative approach to miniaturization has been developed that does not
rely upon increasing microtiter plate densities. Gel-permeation assays, or
iginally developed for screening interactions and anti-microbial screening,
are a well-less-technique. Newer approaches extending this technology to e
nable the screening of traditional compound-collections show exceptional pr
omise and offer the potential to convert most (if not all) 96-well assays i
nto this novel high-density format.
