title: One-dimensional electrophoresis using nondenaturing conditions.
abstract: Two protocols for nondenaturing or native gel electrophoresis (i.e., in the absence of denaturing agents, detergent, or urea) are presented in this unit and offer a useful technique for analyzing the native size of proteins, subunit structure, and optimal separation. Mobility of proteins in native gels depends on size, shape, and intrinsic charge. Continuous PAGE is very flexible and permits cationic and anionic separations over a broad range of pH. Discontinuous PAGE is limited to separations of proteins that are negatively charged at neutral pH.
