Figure 3 Crystal structure of the hPRL-R in complex with sAB A8.

Inhibition of sAB binding by hGH or PRL using phage ELISA. Both hGH (left panel) and PRL (right panel) inhibit the interaction between phage-displayed sABs and hPRL-R in a concentration dependent manner.

Figure 4 sAB inhibition of hPRL-R in T47D breast cancer cells.

A Stat5 phospholyration luciferase reporter assay of T47D cells in the presence or absence of hPRL and hPRL-R sABs. A sAB against bacterial maltose binding protein (MBP) was used as a negative control.
