Human immunodeficiency virus type-1 (HIV-1) DNA and messenger RNA sequences in both cell lines and blood obtained directly from HIV-1-infected patients were amplified by polymerase chain reaction and hybridized to fluorescein-labeled probes in situ, and the individually labeled cells were analyzed by flow cytometry. After flow cytometric analysis,(More)
Determinations of plasma HIV viral RNA copy numbers help to define the kinetics of HIV-1 infection in vivo and to monitor antiretroviral therapy. However, questions remain regarding the identity of various infected cell types contributing to this free virus pool and to the in vivo lifecycle of HIV during disease progression. Characterization of a novel(More)
Cell bioprocessing in space consists of the preparation, cultivation, purification and investigation of cells and their products in the microgravity environment of orbital space flight. Inertial acceleration is used as an independent variable to explore the limits of specific bioprocessing functions, such as cell growth and secretion, gravity-dependent(More)
Molecular approaches to diagnostic questions in clinical medicine are greatly impacting the way researchers and clinicians investigate and treat disease. By combining molecular techniques with classical immunologic tools such as flow cytometry (FCM; 1-3), one can begin to more fully understand and appreciate the role of cellular heterogeneity in disease(More)
Cellular autofluorescence affects the sensitivity of flow cytometric assays by interfering with detection of low level specific fluorescence. These detection limits increase with use of protocols, such as thermocycling and fluorescent in-situ hybridization (FISH), that can increase intrinsic cellular fluorescence to 5,000-20,000 fluorescein isothiocyanate(More)
The glucose oxidase antiglucose oxidase (GAG) immunoenzymatic staining procedure has been used to detect herpes simplex virus (HSV) antigens microscopically. In this study, the GAG procedure was adapted to cells in suspension, and its potential usefulness in flow cytometry was examined. HSV-2 infected monkey kidney and HSV-2 transformed mouse cells were(More)
Human immunodeficiency virus type 1 (HIV-1) infection of T cells and cells of the monocyte/macrophage lineage requires a specific interaction between the CD4 antigen expressed on the cell surface and the HIV-1 external envelope glycoprotein (gp120). To study the association between HIV-1 infection and modulation of cell surface expression of the CD4(More)
