Anti-Human ERBB3 Recombinant Antibody (3D4) (CAT#: TAB-0509CL)
The anti-Her3 antibody specifically target Her3 which is a member of the ErbB protein family. By binding to the Her3, the specific antibody can be used in the treatment of proliferative disorders like cancer.

Figure 1 Activation of NRG1-dependent HER3 abolishes inhibitory effects of trastuzumab in BT474 cells.
p-HER3 was significantly downregulated by HER3 antibody after NRG1 stimulation.

Figure 2 The NRG1-dependent HER3 antibody promotes early apoptosis in BT474 cells.
Without NRG1 stimulation, trastuzumab significantly increased early apoptosis of BT474 cells when compared to the control (P<0.05).

Figure 3 HER3 antibody combined with trastuzumab synergistically inhibits cell viability.
In BT474 cells, the inhibitory effect of trastuzumab on cell viability was gradually enhanced with the increase of drug concentration. However, the effect on MDA-MB-453 cells was weak and stable. After NRG1 combined with trastuzumab, the cell viability was significantly increased in BT474 cells, however, this significant increase was not observed in MDA-MB-453 cells.
