Figure 4From: Bacterial cytoplasm as an effective cell compartment for producing functional VHH-based affinity reagents and Camelidae IgG-like recombinant antibodies Identification of the membrane receptor HER2 by immunofluorescence. The IF staining pattern of the VHH A10 fused to either myc (periplasmic expression) or Fc (cytoplasmic expression) was compared with that of trastuzumab in HER2 neg and HER2 pos cells.Back to article page
