Population genetics of alpha1-antitrypsin in the Netherlands. Description of a new electrophoretic variant.

Two groups of 708 healthy blood donors and 563 patients affected with chronic obstructive lung disease (C.O.L.D.) respectively, have been screened for α1-antitrypsin (α1AT) variants by electrophoresis on agarose-polyacrylamide gels at pH 4.7 and isoelectric focusing (IEF).
