Abstract

Potentially, silver development could unify most modern demands for clean, accurately localized marker amplification in microscopy and bioanalysis. However, the existing technology leaves room for improvement in developer design. A new formulation has been devised which, by using principles of silver chelation, avoids problems of self-nucleation and catalysis by light. It is made, just before use, by mixing together equal amounts of stock solutions containing high molarity, Tris-buffered silver nitrate and alcoholic, buffered pyrogallol. The two stocks are easily prepared and have very long shelf-lives. The developer is light insensitive for up to an hour at room temperature, so that development can proceed under ambient light conditions and at the neutral pH most suited to biological systems. The powerful reducer in the suggested formulation should allow the detection of low concentrations of marker signal in a wide range of applications.
