Figure 3

Fine epitope mapping of 108-B6 and 4A68 antibodies. (a) Schematic diagram of recombinant PGRMC1 fragments (residues 1–25, 1–43, 1–95, 1–157, 1–170, 1–182 and 1–195) used in this study. (b) A series of depletion mutants of PGRMC1 gene were synthesized and separated by agarose gel electrophoresis. The deletion mutants of PGRMC1 genes were detected by ethidium bromide staining. (c) Individual fusion proteins were expressed in E. coli DH5α as fusion proteins with GST tag at the N-terminus, and stained with CBB R-250 after SDS-PAGE. (d,f) Western blot analysis of GST-PGRMC1 fusion proteins with anti-GST (d), 4A68 (e), and 108-B6 (f) antibodies. The asterisks indicate partial degradation products of GST-PGRMC1 fusion proteins.
