Abstract There are many methods employed to precipitate proteins out of solution. In this experiment we manipulated many physical and chemical variables in order to achieve purification of a protein via precipitation. In the first part of the experiment we purified the protein casein by modifying it’s pH. In the second part of the experiment we manipulated the ionic strength of albumin in egg whites‚ in a process called salting out. By manipulating these chemical properties we were able to

Regarding of multiple valuation (Chart 3)‚ P/E ratio from comparable firms are used‚ which leads us to an exchange ratio at 0.68. Thus‚ our estimation for Amoco’s stand-alone value is from $37.07 to $54.69 per share‚ i.e. 0.46 to 0.68-exchange ratio. As the acquirer‚ our basic negotiating strategy is to low the exchange ratio as much as possible. Based
