The damage of bovine serum albumin (BSA) under ultrasonic irradiation in the presence of hematoporphyrin (HP) was studied by UV and CD spectra and the influence of irradiation time, HP concentration, ionic strength and acidity was also detected. The results showed that under a certain condition, the damage degree of BSA was increased with the enhancement of the irradiation time and HP concentration, while the influence of ionic strength and acidity was complicated. The research results were of great significance for driving sonodynamic treatment to clinic application.

Key words: ultrasound, hematoporphyrin, bovine serum albumin
