Investigators decide to analyze the purity of a preparation of antibody molecules using sds polyacrylamide-gel electrophoresis (sds-page). on lane 1 of the gel, they load a sample of the antibody. on lane 2, they load an antibody sample that has been treated with a reducing agent called mercaptoethanol, which breaks disulfide linkages. following electrophoresis, they see distinct bands representing polypeptides with molecular weights of 50 kd and 25 kd in lane 2 and only one band weighing 150 kd in lane 1. what can the investigators conclude about their antibody based on the results of this experiment
