title: PCNA (cyclin) autoantibodies and monoclonal antibodies reveal similar patterns of cyclin (PCNA) antigen staining in human cultured cells.
abstract: Double immunofluorescence and [3H]thymidine autoradiographic analysis of the same field of transformed human amnion cells (AMA) reacted with proliferating cell nuclear antigen (PCNA) autoantibodies and a monoclonal antibody (mAb 19F4) specific for cyclin (PCNA) revealed similar patterns and sequence of cyclin (PCNA) antigen staining during S-phase. These results suggest that immunofluorescence patterns obtained with PCNA autoantibodies reflect in fact patterns of cyclin (PCNA) antigen staining.
