These are the serum protein electrophoresis patterns of six patients (a through f) . The bottom pattern is the "normal" pattern. Identify the anode and cathode sides. Identify albumin, each of the globulins (alpha 1, alpha 2, beta and gamma), the application point and the direction of migration. Which pattern would be consistent with a diagnosis of multiple myeloma (monoclonal gammopathy)…EXPLAIN YOUR REASONING!
