Flow cytometric detection of specific genes in genetically modified bacteria using in situ polymerase chain reaction.
Use of the polymerase chain reaction, coupled with flow cytometry, to detect a plasmid encoded xylE gene sequence in intact cells of Escherichia coli and Pseudomonas putida was investigated. Optimal incorporation of fluorescently labelled dUTP into a full length PCR product required substitution at a level of 2:3 dUTP:dTTP. Formaldehyde fixed cells of both species were counted before and after ...
متن کاملComparison of Two Flow Cytometric Methods for Detection of Human Invariant Natural Killer T Cells (iNKT)
Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...
متن کاملFlow cytometric assessment of viability of lactic acid bacteria.
The viability of lactic acid bacteria is crucial for their applications as dairy starters and as probiotics. We investigated the usefulness of flow cytometry (FCM) for viability assessment of lactic acid bacteria. The esterase substrate carboxyfluorescein diacetate (cFDA) and the dye exclusion DNA binding probes propidium iodide (PI) and TOTO-1 were tested for live/dead discrimination using a L...
متن کاملFlow cytometric analysis of marine bacteria with hoechst 33342.
We investigated the accuracy and precision of flow cytometric (FCM) estimates of bacterial abundances using 4', 6-diamidino-2-phenylindole (DAPI) and Hoechst 33342 (HO342, a bisbenzamide derivative) on paraformaldehyde-fixed seawater samples collected from two stations near Oahu, Hawaii. The accuracy of FCM estimates was assessed against direct counts by using epifluorescence microscopy. DAPI a...
متن کاملFlow cytometric detection of cell-associated cytokines in alveolar macrophages.
To elucidate the cytokine-producing capacity of alveolar macrophages (AMs), we have introduced a method of flow cytometry combined with saponin treatment to detect the cell-associated cytokines. We studied bronchoalveolar lavage fluid cells from six patients with sarcoidosis (SAR) and six control (CTL) subjects. Cells were either left uncultured, or cultured with and without lipopolysaccharide ...
