Beschreibung

Anwendung

Basic fuchsin has been used as a lignin-detecting fluorogenic dye for fluorescence-based imaging of lignin in the basal internodes of three Brachypodium distachyon ecotypes.[1]

Biochem./physiol. Wirkung

Basic fuchsin belongs to the triphenylmethane group. Combining basic fuchsin with sulfurous acid results in the formation of fuchsin sulfurous acid, also referred to as Feulgen reagent or Schiff′s reagent. This reagent is responsible for the staining of chromosomal DNA.[2][3] Basic fuchsin is also used for the staining of lignin in plant tissue samples.[4]

Eignung

Zertifiziert für die säurefeste Färbung mit Karbol-Fuchsin, als ENDO Medium und als Schiffs Reagens in den Periodsäure-Schiff (PAS)- und Feulgen-Techniken.
