Fig 10. Labeled DrBoNT internalization in the presence of labeled Hn33.
Polarized HBE cell monolayers were incubated with DrBoNT-488 and Hn33-PacBlue for 1.5 h. Cells were fixed and then imaged. (a) Hn33-PacBlue (red); (b) DrBoNT-488 (green), and (c) Hn33-PacBlue and DrBoNT-488 merged. Arrows point to the punctations showing colocalization. (Manders coefficient = 0.6) Red bar = 2 μM.
