Figure 3. The MTT assay.

Figure 3

The MTT assay revealed that the cytoviability of both (A) mouse and (B) human liver cells decreased in proportion to the concentration of Gh-rTDH over different treatment durations. Moreover, we noted that Gh-rTDH damaged liver cells in vitro when the concentration of Gh-rTDH exceeded 10−6 µg/ml.
