WebThe Bradford assay readily measured the protein content of each food, and importantly, the addition of melamine or cyanuric acid to reconstituted milk did not affect the readings. The protein concentrations obtained for reconstituted milk powder were as expected, but those for the cat food were 10–30-fold lower, due to its low solubility. WebThe Bradford assay is based on the use of the dye Coomassie Brilliant Blue G-250, which is frequently abbreviated as Coomassie G-250 or Coomassie Blue. This is one of two Coomassie dyes that are often …
