Figure 5
UV-Vis spectra of different proteins and chemical solutions. (a) Ribonuclease A (at 30 mg ml-1) is non-absorbing at 295 nm. (b) Thermolysin (at 2.5 mg ml-1) absorbs at 295 nm. (c) Haematin (at 0.21 mM) absorbs at both 295 and 320-350 nm. (d) FeCl3 absorbs at both 295 and 320-350 nm. (e) Sodium nitrate absorbs at 295 and 320-330 nm. For all graphs, the vertical line is at 295 nm and the vertical band is between 320 and 350 nm.  [article HTML]
