description We have conducted a study of a novel monoclonal A3 antibody raised by means of hybridoma biotechnology. The study was performed with malignant cells of the patients with various lymphoproliferative disorders, and persons with nonmalignant diseases, as compared with intact lymphocytes from healthy people,using a method of immunocytochemical staining and indirect immunofluorescence technique. It was found that in cases of lymphoproliferative diseases with low proliferation rates, as based on the numbers of Ki-67 positive cells, as well as in non-malignant blood diseases, the A3 antigen was localized in nucleoli, and it was visualized as focal fluorescence. In malignant lymphoproliferative diseases with high proliferation indexes, the number of brightly fluorescent foci is observed, with formation of necklace-like structures within the nucleolar structures. The obtained data point to a diagnostic significance of A3 Mab in assessment of cellular proliferative rates in patients with various lymphoproliferative diseases. It was established that, in contrast to Ki-67, the proliferation stage could be determined for each cell, according to the number of fuorescent foci in nucleoli. This specific property of the A3 antigen points to its significance for diagnostics and malignancy staging of lymphoproliferative disorders.
