Abstract: An antibody against spike protein of SARS-CoV-2 is provided, the antibody having a specific heavy chain variable region and a specific light chain variable region, or a fragment of the antibody, the antibody or fragment thereof inhibiting the binding between the spike protein of SARS-CoV-2 and ACE2, the antibody or fragment thereof inhibiting SARS-CoV-2 infection; and a pharmaceutical composition including the antibody or fragment thereof and a pharmaceutically acceptable carrier, the pharmaceutical composition including two or more kinds of the antibody or fragment thereof.

Abstract: Isolated antibodies have been characterized which show specific affinity to a repeating conformational epitope of a protofibril form of the human ?-amyloid peptide as compare to low molecular weight forms of ?-amyloid peptide. These isolated antibodies and related pharmaceutically effective compositions may be useful in the therapeutic and/or prophylactic treatment of Alzheimer's disease by effectively blocking the ability of the protofibril form of ?-amyloid peptide to form fibril forms linked with complications associated with Alzheimer's disease. The isolated antibodies of the present invention are also useful in various diagnostic assays and associated kits.
