You have been given a batch of proteins potentially related to your unknown protein. The proteins are given to you as 10mM solutions in phosphate buffer. You acquire UV-Vis spectra of the solutions to compare to your unknown mixture. A)what is you blank? B)if the extinction coefficient of one of the proteins is 25000M^-1 cm^-1, what will be the absorbance of the solution?
