Figure 1

Determination of haptoglobin phenotypes by Western Blot. In total 159 plasma samples were analysed for haptoglobin phenotype. Figure A shows a membrane with bands correcponding to the alpha-subunits (8.9 kDa/16 kDa) and the betha-subunit (40 kDa) of the haptoglobin protein. The membrane shows bands for the pooled human haptoglobin, the two Hp:Hb complexes (Hp1-1:Hb and Hp2-2:Hb) and plasma samples from the cohort corresponding to the Hp1-1, Hp2-1 and the Hp2-2 phenotype in similar band patterns. One lane was cut out from the gel due to individual variation in the haptoglobin concentrations. Figure B, shows a representative membrane of the α-subunits of the haptoglobin protein in different plasma samples as well as the pooled human haptoglobin protein that was included as a positive control on each membrane.
