DNA sequences specific for Caucasian G3m(b) and (g) allotypes : allotyping at the genomic level
Assignment of the G3m(g) and (b) correlative amino acid residues was performed at the genomic level by direct sequencing of DNA from nine Caucasian individuals. Two oligonucleotide primers were used for subclass-specific enzymatic amplification of a DNA segment comprising a major portion of the second and third constant region domains (CH2 and CH3) fo the human IgG3 heavy chain gene.
