Summary. Pig, horse and dog plasma proteins, separated by horizontal polyacrylamide gel electrophoresis (pH 9.0) and electrophoretically transferred to nitrocellulose membranes, were tested for cross‐reaction with antiserum to human plasma α 1 B‐glycoprotein (α 1 B). The results showed that one previously reported polymorphic plasma postalbumin in each of these species (pig PO2, horse Xk and dog Pa protein) was homologous to human plasma α 1 B. In the light of the previously known genetic linkages in these species, this implied: (1) α 1 B gene is close linked to Phi, Pgd and Hal (halothane sensitivity locus) loci in pigs; and (2) α 1 B gene is linked to MEl and Phi loci in horses. This suggested that the α 1 B gene may also be found to be closely linked to gene(s) controlling susceptibility to malignant hyperthermia in humans and other mammals.
