title: A new alpha 1-antitrypsin allele PI Poki: isoelectric focusing with immobilized pH gradients as a tool for identification for PI variants.
abstract: A new rare genetic variant PI Poki in the protease inhibitor system found in two Japanese subjects, was compared with some PI P variants using several electrophoresis systems. Although this variant was slightly anodal to P by separator isoelectric focusing, it could be readily distinguished by isoelectric focusing with immobilized pH gradients: the mobility of Poki became cathodal to P. This method proved to be a powerful tool for identification of PI variants.
