    摘要: A method for quantitatively analyzing a biochemical compound such as glucose or cholesterol is performed by bringing the biochemical compound into contact with double stranded DNA fragments which are fixed onto a surface of an electrode at their one terminals and in which electrochemically active threading intercalators are intercalated, in an aqueous medium under application of electric potential to the electrode in the presence of an oxidase capable of oxidizing the biochemical compound and becoming a reduced oxidase, and detecting an electric current flowing between the electrode and another electrode placed in the aqueous medium.

    摘要: A silver halide photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a light-insensitive uppermost layer is disclosed. The light-insensitive uppermost layer has a melting time longer than that of the light-sensitive silver halide emulsion layer and the thickness of the light-insensitive uppermost layer is from 1.3 .mu.m to 5.0 .mu.m. The silver halide photographic light-sensitive material has an improved covering power and results in remarkably low degree of reticulation. Furthermore, when the material is used it results in a reduced amount of scum being formed in the processing solution.
