Figure 4. Immunocytochemistry using fluorescently labeled BC2 nanobody.

Figure 4

(a) Schematic representation of BC2-tagged fusion proteins and fluorescently labeled BC2-Nbs used for co-localization studies. The BC2T sequence was genetically fused to the C-terminus of mCherry-Vimentin (mCherry-VIMBC2T) and eGFP-PCNA (eGFP-PCNABC2T). (b) HeLa cells ectopically expressing mCherry-VIMBC2T or eGFP-PCNABC2T were fixed either with methanol or PFA, respectively, followed by staining with the indicated fluorescently labeled BC2-Nbs and DAPI. Scale bar 25 μm.
