Abstract
An isoelectric focusing (IEF) procedure in an ultra-narrow pH range, 4.2–4.9, has been utilized to detect α1-antitrypsin or α1-protease inhibitor (PI) allele products in 2 US white and 3 US black populations as well as 1 native African black population. In addition to the 3 common alleles PI*M1, PI*M2 and PI*M3, products of the 4th allele PI*M4 have been identified in US whites at low-level frequency. The presence of the PI*S, PI*Z and PI*I alleles has also been verified in our population samples. While the PI*S allele is present at a polymorphic level in US whites, it is only present sporadically in US blacks and is completely absent in African blacks. The PI*Z allele was not detected in the black populations tested. The PI allele frequency data have been used to calculate white admixture in US blacks.
