ABSTRACT:
Preparation of an immunoassay gel substrate which includes the steps of depositing on an immobilizing support structure a liquid mass of a gel-forming emulsion which coalesces into a thick gel-like matrix film characterized by substantial non-agglomerated matrix homogeneity, treating the resulting film to alter matrix homogeneity by agglomerating particles which form part of the gel, and as a consequence of the treating step establishing the object gel. Treating may be performed either by subjecting the gel to multiple time-vigorous water-wash and dry cycles, by emersing the gel in water for a relatively long period of time, or by wetting the gel and then subjecting it to one or more freeze/thaw cycles.
