Binding of harmane to human and bovine serum albumin: fluorescence and phosphorescence study [PDF]

, 2012
The binding of harmane with human serum albumin (HSA) and bovine serum albumin (BSA) were studied by fluorescence and phosphorescence spectroscopic methods. Quenching of fluorescence of serum albumins by harmane was found to be a static quenching process.
