Abstract
A monoclonal antibody that recognizes antigenic determinants on the nucleus of cultured mammalian cells was isolated. Immunofluorescence studies using this antibody showed that the recognized antigen was present not only on the nucleus but also in cytoplasmic vesicles of interphase cells and in the perichromosomal region of mitotic cells. Premature chromosome condensation analysis showed that the reactive site for this monoclonal antibody could be detected in the perichromosomal region during the G2 and M phases, but not during the G1 and S phases. Finally, immunoblot analysis showed that this monoclonal antibody prepared against the nucleus recognized a protein of approximately 40 kD both in the cytoplasm and in the perichromosomal regions.
