Implication

Methodological study demonstrates nanogram-level detection of plant proteins and nucleic acids in polyacrylamide gels, highlighting enhanced visualization of low-abundance viral antigens.

Key Points

To develop a sensitive silver staining protocol utilizing thiosulfate chemistry to detect proteins, RNA, and DNA in polyacrylamide gels without background staining.
Pretreated fixed polyacrylamide gels with thiosulfate for image enhancement and to form soluble silver complexes that suppress unspecific background staining during image development.
Evaluated staining sensitivity across one- and two-dimensional electrophoretic separations of plant leaf proteins and tobacco mosaic virus-infected protoplasts.
Achieved high detection sensitivity in the nanogram range for proteins, RNA, and DNA against a colorless, transparent gel background.
Successfully detected the non-structural, tobacco mosaic virus-specific 126 kDa protein directly within the one-dimensional electrophoretic pattern of infected protoplasts.
