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.
