The hereditary deficiency variants of alpha 1-antitrypsin that are associated with diseases such as emphysema are usually identified by use of isoelectric focusing on polyacrylamide gels. Agarose is a simpler, faster, safer, and more reliable medium for this, but resolution

The polymorphism of alpha-1-antitrypsin (PI) has been studied by hybrid isoelectric focusing in miniaturized immobilized pH gradient gels, with an interelectrode distance of 55 mm, in two narrow ranges of pH 4.35-4.75 and 4.35-4.55), following rehydration with pH 4.2-4.9 carrier
