In the Bradford protein determination, the color of a dye changes from brown to blue when it binds to a protein. The intensity of blue color (measured by absorbance of light at a wavelength of 595nm) is proportional to protein concentration. Protein (ug) Absorbance at 595nm 0.00 0.466 9.36 0.676 18.72 0.883 28.08 1.086 37.44 1.280 Use Excel to determine the equation of the line in the format of y = mx + b. (I tried y=0.0218x+0.4706 and it was wrong) Using the calibration curve for the Bradford protein determination in the previous question, determine the number of micrograms of protein in an unknown if it gave an absorbance of 0.973. I tried 23.505 and it was wrong
Fill the table given the info below. Please thank you. Protein at 1 mg/mL which is also 1g/L. Use the DNA sequence below to export to ExPASy Translate & ProtParam.
