|Description||Pertuzumab (anti-HER2), a humanized monoclonal antibody and the first in the class of agents called the HER2 dimerization inhibitors, impairs the ability of HER2 to bind to other members of the HER family, MW: 148 KD.|
Pertuzumab (anti-HER2) significantly inhibits the HRG-α-stimulated cellular growth of the 11_18 cells. Pertuzumab blocks HRG-α-stimulated phosphorylation of HER3, mitogen-activated protein kinase (MAPK), and Akt. In contrast, pertuzumab fails to block epidermal growth factor (EGF)-stimulated phosphorylation of EGF receptor (EGFR) and MAPK. Immunoprecipitation shows that pertuzumab inhibited HRG-α-stimulated HER2/HER3 heterodimer formation. HRG-α-stimulated HER3 phosphorylation is also observed in the PC-9 cells co-overexpressing EGFR, HER2, and HER3, but the cell growth is neither stimulated by HRG-α nor inhibited by pertuzumab. Pertuzumab binds to ErbB2 near the center of domain II, sterically blocking a binding pocket necessary for receptor dimerization and signaling. Pertuzumab is specific for human ErbB2 and does not bind to rodent ErbB2 (neu) with detectable affinity.
|In vivo||Pertuzumab (anti-HER2) has antitumor activity as a single agent in a mouse xenograft model and the combination with trastuzumab strongly reduces EGFR-HER2 signaling and shows significant antitumor activity compared with each monotherapy in NCI-N87, an HER2-positive human gastric cancer xenograft model.|

Frequently Asked Questions
How to store the antibody?
Store the undiluted solution at 4 °C in the dark. Freezing antibodies can result in a loss of activity caused by the freezing/thawing process. Diluting antibodies to working concentrations and storing at 4°C for more than a day should be avoided. Additionally, make sure to keep the antibody sterile. Under these storage conditions, your antibodies should remain active for up to one year and oftentimes longer.
