Biochem/physiol Actions

Janus Green B belongs to the phenazine group of dyes. It is a dark green/dark brown/dark black powder. Janus Green B should be oxidized to become colored. Thus, this dye can be used to specifically stain mitochondria in living cells. It has been used to stain biomolecules, nucleic acids and chromosomes. In addition, it is also used to stain various living organisms including fungi, yeast cell, brain, spinal cord, sperms and tissue culture monolayer. Janus Green B acts as an antimalarial agent. It also facilitates diagnostic assays and diagnosis of disease related to amyloid accumulation.

Current methods of monitoring insulin in culture are limited to soluble insulin (secretions or lysates) or synthetic gene reporter analyses. We present an insulin-specific cell enzyme-linked immunosorbent assay (cell-ELISA) to assess relative intracellular insulin protein content of adherent cultures, normalized...
