Research highlights
1. Developed the flow cytometric methodology to differentially stain DNA versus DNA with acridine orange. This methodology was applied to distinguish the non-cycling (resting; G0 cells> from their cycling counterparts, such as peripheral blood lymphocytes from mitogenically stimulated lymphocytes.[1]
2. Developed the flow cytometric methodology to identify apoptotic cells based on labeling DNA strand breaks with exogenous terminal deoxynucleotidyl transferase (the TUNEL assay)[2][3]
3. Developed the flow cytometric methodology to detect DNA denaturation in situ based on use of the metachromatic properties of acridine orange[4]
4 Used this methodology to detect abnormality of chromatin structure of infertile sperm cells[5][6] This methodology is currently being used as one of the key methods to assess male fertility in animal and human clinic [7]
5. First reported that abnormal, infertile human sperm cells have extensive DNA fragmentation being detected by the TUNEL assay[8] This methodology now serves also as the means of identification of abnormal, infertile sperm cells.
6. Developed still another assay to identify apoptotic cells by flow cytometry, based on the use Fluorochrome Labeled Inhibitors of Caspases (the FLICA assay)[9]
7. Developed the methodology to detect potential cancerogenic properties of tobacco smoke by measuring the smoke-induced DNA damage reported by phosphorylation of histone H2AX and activation of ATM in individual cells by flow cytometry[10][11]
