Figure 3From: Delineation of the Pasteurellaceae-specific GbpA-family of glutathione-binding proteinsCharacterization of the hemin-binding properties of GbpA and HbpA2 family members. Native-PAGE analysis of 10 μg test protein in the absence (-) or the presence (+) of 0.5 mM hemin. The faster migrating band for each test protein in the presence of hemin represented the hemin/protein complex as verified by heme-staining (see Materials).Back to article page
