Abstract:
본 발명은 마이코플라스마 감염된 혈중암세포를 인식할 수 있는 단일클론항체 CA27 및 이를 이용한 마이코플라스마 감염된 혈중암세포 검출방법에 관한 것으로서, 상기 단일클론항체 CA27은 마이코플라스마 p37 단백질을 특이적으로 인식하므로, 암환자의 혈중에 마이코플라스마로 감염된 혈중암세포의 존재 여부를 확인할 수 있기 때문에, 암환자 치료 시에 암 전이 가능성에 대한 조기 예측이 가능한 장점이 있다.
Abstract:
PURPOSE: A monoclonal antibody which specifically binds to undifferentiated human embryonic stem cells and a hybridoma producing the same are provided to study human embryonic stem cells. CONSTITUTION: A monoclonal antibody 297-D4 which is specific to undifferentiated human embryonic stem cells contain heavy chain variable domain(VH) with an amino acid sequence of sequence number 1 and a light chain variable domain(VL) with an amino acid sequence of sequence number 2. The monoclonal antibody is IgG1.k isotype and recognizes undifferentiated human embryonic stem cell BAP31-like proteins. A composition for removing the stem cells contains monoclonal antibody 297-D4. A kit for detecting the stem cells contains 297-D4. A method for isolating the stem cells comprises: a step of adding the monoclonal antibody 297-D4 to a cell group; and a step of isolating cells which combined with the monoclonal antibody 297-D4.

CONSTITUTION: A monoclonal antibody which is specific to human embryonic stem cells contains heavy chain variable region of amino acid sequence number 6 and light chain variable region of amino acid sequence number 7. A kit to detecting undifferentiated human embryonic stem cells contains a monoclonal antibody 2-E2. A composition for removing the undifferentiating human embryonic stem cell contains the monoclonal antibody 2-E2.
Abstract:
PURPOSE: A monoclonal antibody which specifically binds to undifferentiated human stem cells is provided to research difference of initial embryo development between rat and human. CONSTITUTION: An undifferentiated human embryonic stem cell-specific monoclonal antibody 247-B9 contains variable region of heavy chain having an amino acid of the sequence number 6 and variable region of light chain having an amino acid of the sequence number 8. The monoclonal antibody 247-B9 recognizes about 37kDa protein of undifferentiated human embryonic stem cell and hnRNP A2/B1 analog protein. A composition for removing the undifferentiated human embryonic stem cell contains the monoclonal antibody 247-B9.
Abstract:
PURPOSE: A monoclonal 57-C11 which specifically binds to undifferentiated human embryonic stem cells is provided to remove the stem cell during cell therapy. CONSTITUTION: An undifferentiated human stem cell-specific monoclonal antibody 57-C11 contains variable region of heavy chain(VH) having amino acid of the sequence number 6 and variable region of light chain(VL) having amino acid of the sequence number 8. A hybridoma which produces the monoclonal antibody 57-C11 or its antigen binding site contains B cell fused in immortalized cells from transformed non-human animal which has genome containing heavy chain and light chain transgenes.
