  • High resolution electrophoretic gel and method for separating serum proteins
    Patent number: 4857163
    Abstract: A novel agarose gel is provided for use in the high resolution electrophoretic (HRE) separation of serum proteins. The agarose gel employs a novel gel buffer which contains either hippurate, glycine, or a mixture thereof, in combination with barbital and Tris. The agarose gel of the present invention yields improved electrophoretic separation of the serum proteins in a sample whether the same gel buffer is also used as the running buffer or whether a standard barbital running buffer is used.
