    A biochemistry laboratory student used the Bradford protein assay to measure the lysozyme (protein) content in egg whites. The Bradford protein assay is a spectrophotometric technique that uses a dye, Coomassie Brilliant Blue, whose absorption undergoes a spectroscopic shift when bound to a protein. In the unbound state, Coomassie Brilliant Blue displays a red color. As protein binds to the dye, its absorbance at 595 nm increases and the dye changes to a blue color. The student prepared a 3.900...
