0.3 ml of a protein solution was diluted with 0.9 ml of water. To 0.5 ml of this diluted solution, 4.5 ml of BCA reagent was added and the color was allowed to develop. The absorbance of the mixture at 562 nm was 0.23 in a 1 cm cuvette. A standard solution (0.5 ml, containing 4 mg of protein per ml) plus 4.5 ml of BCA reagent gave an absorbance of 0.06 in a same-sized cuvette. What is the protein...
