Figure 3.

The transfection rate of DV1–BH3, TAT–DV1, and TAT–DV1–BH3 in MDA-MB-231, MCF-7, and HEK-293 cells.

Notes: The histogram of the transfection rate of the three fused polypeptides. Cells were exposed to 20 μM DV1–BH3, TAT–DV1, or TAT–DV1–BH3 for 1 hour and washed with PBS. Then, the cells were subject to flow cytometry. The number of green fluorescent cells was quantified, and the transfection rates were calculated.

Abbreviations: BH3, Bcl-2 homology 3; TAT, transactivator of transcription; PBS, phosphate-buffered saline.
