Figure 1. Uptake of 5-FAM tagged IC2B peptide into pulmonary artery smooth muscle cells.

Figure 1

The chemical structure of SynB3RG transporter sequence attached to IC2 loop of the ETB receptor is illustrated in (A). Flow cytometry shows that 5-FAM tagged IC2B peptide entered the cells efficiently after 20 mins of exposure (B).
