Protein Electrophoresis aka serum protein electrophoresis test is done to identify some unique kind of protein in the body to detect specific diseases. Protein is a substance made up of smaller blocks called amino acids. Protein electrophoresis uses an electric field to pick up the proteins from the blood serum in the groups of shape, size, and charge. The blood serums in the human body contain two types of proteins, albumin, and globulin. Protein electrophoresis breaks down these two proteins into further five smaller categories Albumin Alpha 1 globulin Alpha 2 globulin Beta globulin Gamma globulin
