Experiment 18 Western Blot to Identify an Antigen

We suggest that steps 1 through 6 be performed by the instructor prior to the beginning of the experiment. We perform this experiment in conjunction with Experiment 18 ( Western Blot to Identify an Antigen ). If this option is chosen, the protocol described above can be followed exactly. If the Western blot is not to be performed, the SDS-PAGE experiment described in Experiment 18 can be performed on a single set of samples (see step 16).
