WebJul 31, 1992 · Using flow cytometry, monoclonal antibodies to the HIV proteins p24, gp41 and p17 were evaluated for their ability to detect HIV antigens associated with HIV-infected T cells. Mixtures containing varying ratios of HIV-infected and uninfected cells were subjected to analysis with these monoclonal antibodies. WebThe effectiveness of these two assays for quantitation of FMH was compared with flow cytometry (FC). Materials and methods: Standard anti-D FC was performed to quantitate fetal D-positive cells in D-negative women and compared with FMH estimated by AE and HbF FC. Results: HbF FC distinguished F cells from fetal cells. hikvision digital video recorder instructionsWebThus, a reliable method to quantitatively assess FMH is necessary. Study design and methods: Serial dilutions of artificial FMH were quantitatively measured by three different methods: flow cytometry, fluorescence microscopy (each after anti-D staining), and by the Kleihauer-Betke test. small wood burning cooking stove
