Complex formation between Chromatium vinosum ferric cytochrome c' and bromophenol blue.


An unusual complex has been observed between the common electrophoresis tracer bromophenol blue (BPB) and the cytochrome c' from Chromatium vinosum during polyacrylamide gel electrophoresis. Complex formation results in a shift and increase in the intensity of the visible absorption band of BPB. Differential spectrophotometric titration of BPB with… (More)
