Summary
A combination of immunoblotting and polyacrylamide gel isoelectric focusing (IEF-PAGE) was used to define a new genetic variant in the (GC) group-specific component system. This appeared to be a GC 1-type variant, and was presumed to have arisen from duplication of the GC 1F and GC 1A2 genes.
