Exercise 1: Standard Curve for Protein Measurements:
A standard curve for protein concentration is often created using known concentrations of bovine serum albumin (protein).
This process is called the Bradford Assay; it is a colorimetric assay. A special reagent turns blue when it binds to amino
acids present in protein. The intensity of the color is best measured with a spectrophotometer (a device for comparing two
light radiations, wavelength by wavelength). In the case of the Bradford Assay the greater the absorbance, the higher the
protein concentration.
A series of tests were performed on some samples and
