Application

Silver nitrate has been used for Von Kossa staining for evaluating the mineralized matrix. It has also been used for staining culture for assessing mineralization during osteogenic differentiation. Additionally, it has also been utilized in the staining of nucleic acids and of glycoconjugates in gels.

Biochem/physiol Actions

Silver nitrate is an inorganic compound that induces the protein conformational condition of amyloid A amyloidosis in mice. It also possesses antibacterial activity against Gram-negative and Gram-positive bacteria and antimicrobial activity against periodontal pathogens. Further, it enhances the shoot development as well as plant regeneration of chillo pepper (Capsicum annuum L.) through organogenesis.

Alcian blue and toluidine blue dyes form complexes with anionic glycoconjugates (AG) such as proteoglycans (PG) and glycosaminoglycans (GAG). However, the Alcian blue-AG complexes do not readily dissociate, while the toluidine blue-AG complexes do so in salt solutions. This differential...
