Abstract
The identification of group specific component (Gc) subtypes derived from bloodstains by separator isoelectric focusing in micro-ultrathin polyacrylamide gels (interelectrode distance: 50 mm) containing 4.5 to 5.4 pharmalytes is described. The separation achieved between Gc 1F and Gc 1S bands is compared favorably with that obtained using separator isoelectric focusing in conventional polyacrylamide gels dimensions (interelectrode distance: 110 to 120 mm). The technique is rapid and economical, and the immunoblotting method described is more sensitive than immunofixation followed by silver staining.Keywords
