Demonstration of “naturally occurring mitochondrial antibodies” in family members of patients with primary biliary cirrhosis
Reinhild Klein, Peter A. Berg – 1 August 1990 – Sera from 81 healthy family members (including husbands) of 13 patients with primary biliary cirrhosis were tested by Western blotting against the antigen fractions M9 and M2 derived respectively from rat liver and beef heart mitochondria. Fifty‐eight (70%) were positive and recognized four major (molecular weights 98 kD, 65 kD, 61 kD, 58 kD) and eight minor determinants (85 kD, 81 kD, 78 kD, 54 kD, 48 kD, 45 kD, 40 kD, 30 kD) labeled α‐my. Each of the 58 sera recognized at least one of the four major polypeptides.
