The polymorphism of the vitamin D-binding protein (Gc); isoelectric focusing in 3 M urea as additional method for identification of genetic variants.
Since the last report numerous new DBP (Gc) variants have been observed; at present a total of 84 different mutants can be distinguished. Several of them have similar electrophoretic mobilities and/or isoelectric points of conventional isoelectric focusing (IEF). IEF in polyacrylamide gels in the presence of 3 M urea is a convenient and efficient method for the detection of hidden variation.
