Application

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.

Actions biochimiques/physiologiques

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. Basic fuchsin is also used for the staining of lignin in plant tissue samples.

Adéquation

Certified for use for acid-fast staining with carbol-fuchsin, as ENDO medium, and as Schiff′s reagent in the Periodic Acid Schiff (PAS) and Feulgen techniques.

The intimate association of host and fungus in arbuscular mycorrhizal (AM) symbiosis can potentially trigger induction of host defence mechanisms against the fungus, implying that successful symbiosis requires suppression of defence. We addressed this phenomenon by using AM-defective vapyrin (vpy)

A superparamagnetic graphene-Fe(3)O(4) nanocomposite (G/Fe(3)O(4)) was synthesized by a facile one-pot solvothermal method. The nanocomposite G/Fe(3)O(4) prepared by the new method was firstly used as an adsorbent to remove dye for water pollution remediation. In comparison with G/Fe(3)O(4) prepared by
