title: Variants of the group-specific component system as demonstrated by immunofixation electrophoresis. Report of a new variant, Gc Boston (Ge B).
abstract: Immunofixation electrophoresis is a relatively simple and reliable method for the genetic phenotyping of the group-specific component (Gc) of serum. This method permits direct comparison of electrophoretic mobilities and band concentrations, with no interference by other proteins. The variants Gc Ab and Gc Y appear identical by this technique; the Eskimo variant appears to be similar to Gc D but not to Gc Ab as previously reported. Gc Norway, also designated Gc 1C, is electrophoretically cathodal to the slower band of Gc 1 and therefore appears to be a distinct variant. A new variant, Gc Boston, is single banded with mobility between the two bands of Gc 1.
