Beauty of Protein

We are unable to see protein with our physical eyes, but there's a way we can. Bio-Rad reagents are how I have been able to see protein in my research. When this reagent is added to proteins, a variety of colors is seen based on the concentration. The absorbance of these colorful solutions has been taken during my research and plotted on a graph. Since absorbance is directly proportional to concentration, a graphical representation is taken. There is also a direct correlation to concentration and intensity of color we see of the solution. The more concentration of protein in a solution means the higher intensity of color is seen. Even when you do not know the exact concentration of protein in solution, you can get a rough estimate based on your standard protein array you have. This is seen with the top tubes of unknown concentration.
