Figure 1From: Haptoglobin phenotype prevalence and cytokine profiles during Plasmodium falciparum infection in Dogon and Fulani ethnic groups living in MaliDetermination 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.Back to article page
