By means of immunoelectrophoresis with anti-WL serum, the serum components of domestic fowls used (White Leghorn, Barred Plymouth Rock, New Hamdshire, Rhode Island Red and White Cornish) were compared.(1) The serum of WL was fractionated into ten or twelve fractions (Plate I-1).(2) The serum samples obtained from the three varieties (WL, BP and NH) showed same immunoelectrophoretic pattern. On the other hand, the pattern of the varieties (SR and WC) was different from that of the former group of the variety (Plate I-3).(3) The difference of the pattern between two above-mentioned groups was only observed in the α1 region.(4) Moreover, by means of specific staining method and method for absorbed antiserum, the protein showing the difference was determined to be lipoprotein.(5) The precipitarion in the immunoreaction of α1-lipoprotein in WL-group to the corresponding antibody was remarkably stronger than that in the SR-group.(6) The following two hypothesis may be settled for the reason of the abovementioned grouping: (1) quantitative difference of α1-lipoprotein in serum between the two groups; and (2) the difference of the similarity on the antigenic conostrnction of α1-lipoprotein to that of WL serum used in the standard.
