Tryptophan and tyrosine fluorimetry. (A) Effect of apigenin on peroxynitrite (ONOO−)-induced alterations in the tryptophan residues of fibrinogen protein. The tryptophan residues were excited at a wavelength of 295 nm. # p < 0.001 versus native fibrinogen; @ p < 0.05 versus #. (B) Effect of apigenin on peroxynitrite (ONOO−)-induced alterations in the tyrosine–tryptophan residues of fibrinogen protein. The tyrosine and tryptophan residues were excited at a wavelength of 280 nm. # p < 0.001 versus native fibrinogen; @ p < 0.05 versus #.
