Naphthol Blue Black has been used for the staining of western blot membrane for detection of all protein that are transferred to the membrane.[1][2]
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.

PopF1 and PopF2, two proteins secreted by the type III protein secretion system of Ralstonia solanacearum, are translocators belonging to the HrpF/NopX family.
Precise control of gene expression is a powerful method to elucidate biological function, and protein overexpression is an important tool for industry and biochemistry. Expression of the Neurospora crassa tcu-1 gene (NCU00830), encoding a high-affinity copper transporter, is tightly controlled

A method has been devised for the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets. The method results in quantitative transfer of ribosomal proteins from gels containing urea. For sodium dodecyl sulfate gels, the original band pattern was
