Description

Application

Naphthol Blue Black has been used for the staining of western blot membrane for detection of all protein that are transferred to the membrane.

Biochem/physiol Actions

Naphthol blue black dye can be used to stain proteins on polyacrylamide gels, agarose gels and nitrocellulose membranes. After electrophoresis, fixing the proteins in the gel is recommended. The gel can then be stained with 0.1% Naphthol Blue Black in 7% (v/v) acetic acid for at least 2 hr and destained with a soluion of 7% (v/v) acetic acid. Detection sensitivity is approx. 20% that of Coomassie Blue R.
