The virus neutralizing efficacy of HB-C7A, a human monoclonal antibody raised against the surface antigen of hepatitis B virus (HBsAg), was proved using hepatitis B virus (HBV)-naïve chimpanzees. One control chimpanzee which received 100CID(50) of HBV, subtype adw, without HB-C7A antibody became infected by HBV as evidenced by the appearance of HBV DNA on(More)
The epidermal growth factor receptor (EGFR) overexpressed in many epithelial tumors is an attractive target for tumor therapy since numerous blocking agents of EGFR signaling have proven their anti-tumor activity. Here we report a novel monoclonal antibody (mAb), A13, which was generated from mice immunized with human cervical carcinoma A431 cells. In(More)
Hepatitis B virus (HBV) is one of the main pathogens responsible for hepatitis and hepatocellular carcinoma. Human plasma-derived Hepatitis B immune globulin (HBIG) is being used for prophylactic and liver transplantation currently. However, it may be necessary to replace a HBIG with a recombinant one because of limited availability of human plasma with(More)
It is well established that blocking the interaction of EGFR with growth factors leads to the arrest of tumor growth, resulting in tumor cell death. ER414 is a human monoclonal antibody (mAb) derived by guided selection of the mouse mAb A13. The ER414 exhibited a ~17-fold lower affinity and, as a result, lower efficacy of inhibition of the EGF-mediated(More)
OBJECTIVES The epidermal growth factor receptor (EGFR) abnormalities including amplification, mutation, and overexpression are frequent in non-small cell lung cancer (NSCLC). We investigated in vitro and in vivo antitumor activity of ER2, a novel human anti-EGFR monoclonal antibody, in NSCLC. METHODS A panel of NSCLC cell lines (A549, H460, H322, H358,(More)
Based on first-principles density-functional calculations, we propose a class of nearest-neighbor donor pairs that are energetically favorable in highly n-type Si. These donor pairs comprise dopant atoms either fourfold coordinated at the nearest-neighbor distance or threefold coordinated through bond-breaking relaxations. For P and As dopants, the two(More)
