Anti-ERBB2 / HER2 / CD340 Reference Antibody (trastuzumab) on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

The purity of Anti-ERBB2 / HER2 / CD340 Reference Antibody (trastuzumab)is more than 95% ;determined by SEC-HPLC.

Immobilized human HER2; His at 2 μg/mL can bind Anti-ERBB2 / HER2 / CD340 Reference Antibody (trastuzumab);EC50=0.005735μg/mL.

BT474 cells were stained with Anti-ERBB2 / HER2 / CD340 Reference Antibody (trastuzumab) and negative control protein respectively; washed and then followed by PE and analyzed with FACS; EC175=0.3024 μg/mL.

Trastuzumab inhibited the tumor growth of BT474 on NCG mice. The result showed significant anti-tumor effects; with an tumor inhibition rate (TGI) of 88.5% at 10 mpk at D35.
