Rapid Delivery of Nanobodies/V_HHs into Living Cells via Expressing In Vitro-Transcribed mRNA.

ABSTRACT: Intracellular antigen labeling and manipulation by antibodies have been long-thought goals in the field of cell research and therapy. However, a central limitation for this application is that antibodies are not able to penetrate into the cytosol of living cells. Taking advantages of small sizes and unique structures of the single-domain antibodies, here, we presented a novel approach to rapidly deliver the nanobody/variable domain of heavy chain of heavy-chain antibody (V_HH) into living cells via introducing its coding mRNA, which was generated by in vitro transcription. We demonstrated that actin-green fluorescent proteins (GFP) and Golgi-GFP can be recognized by the anti-GFP nanobody/V_HH, vimentin can be recognized by the anti-vimentin nanobody/V_H
