The objective for today was to ascertain the concentration of Adenosine Deaminase via analysis of the UV-vis spectra. Since protein concentrations are difficult to measure Bradford Assay, which is a protein binding dye, will be used. The specific dye used is called Coomassie Blue. Once the dye binds with the protein it undergoes absorption changes. We will be making a calibration curve using the Bradford Assay data for the protein. | |||

The protocol called for 10mg of protein in 2mL of solution. Due to insufficient protein we were only about to use 3.6mg per 2mL which had a final concentration of 1,800 μg/mL. This was then used to create six standard solutions: | |||
