Fig. 5. Subcellular localization of wild-type and FLAG-tagged human and bovine PrP
in BHK cells transfected with recombinant Semliki-Forest virus RNAs. The
subcellular location was determined by immunofluoroscence microscopy employing
the mAb anti-PrP 3B5 and a secondary Ab (goat anti-mouse IgG) conjugated with
indocarbocyanine (Cy3). Immunostaining of non-permeabilized BHK cells (A-F,
left panels) transfected with (A) SFV-1 RNA (without any insert), (B)
recombinant SFV-huPrP1-253 RNA, (C) recombinant SFV-huPrP22FLAG RNA, (D)
recombinant SFV-huPrP227FLAG RNA, (E) recombinant SFV-boPrP1-264 RNA and (F)
recombinant SFV-boPrP239FLAG RNA. (A-F, right panels) Intracellular
immunostaining of permeabilized, transfected BHK cells, respectively.
