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 put it here in the format of y = mx + b.  Start your answer with "y=". 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.  Report answer to the hundredths place.

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.
