Fig. 6. Measurement of NF–B translocation by flow cytometry. Dose-response curve of NF-B translocation after 30 min of LPS treatment of human DCs. Results are expressed as the mean values of MFI, taken from FACS histograms and the SDs were obtained from five experiments
Binding & Internalization

Fig. 1. Green (El, X-axis) vs. red (FL2, Y-axis) fluorescence, showing BCG internalization and binding by T24 bladder carcinoma cells. Incubation of R4 cells with fluoresceinated BCG (10 clu BCG/cell) for a duration of 4 h and subsequent labeling with anti-BCG and PE-conjugated second antibody: FLl +m2- cells (quadrant 4) represent BCG-internalizing cells, FLl+/FL2+ cells (quadrant 3) represent BCG-binding cells.
Isolation of genes from libraries

Fig. 5 After fluorescent labelling using anti-product antibodies the beads were analysed by flow cytometry. The levels of fluorescence (FL1-H) on single unsorted beads are plotted as histograms. The \'positive\' highly fluorescent beads (in region M1) were sorted from the \'negative\' low-fluorescence beads and re-analysed. The genes on the sorted \'positive\' beads (and on unsorted beads) were PCR amplified and analysed by agarose gel electrophoresis

Fig. 3. Evaluation of B- and T-cell apoptosis after LPS activation. /*/. A: Identification of B (54%; B220/CD5-) and T (30%; B220-/CD5) cells after culture/*/ F: Apoptosis (FL-4 fluorescence) and DNA cell cycle, with 11% of the B-cell population apoptotic and in the G0/G1 cell cycle phase and 1% of the B-cell population apoptotic and in the S and G2/M cell cycle phases. D: DNA cell cycle histogram of B cells using DAPI staining, showing 82% in the G0/ G1
TdT- mediated dUTP nick end labelling
Fig. 5. Cytokine responses in nasal lavage from an asthma patient to Rhinovirus-16 inoculation. Specimens were collected on day 0 (before viral inoculation) and 2, 4, and 7 days after inoculation. A 4-plex cytokine CBA assay, consisting of IL-1h, IL-8, GM-CSF, and IL-6 beads was used for these samples. Detectable cytokine concentration changes were observed after Rhinovirus-16 inoculation.

Fig. 3. Detection of GAPDH mRNA and 28S rRNA in living HL-60 cells by FC. QFRET probe sequences are shown. The control probe pair consisted of donor probe for 28S rRNA and acceptor probe for GAPDH. HL-60 cells permeabilized by SLO were incubated with QFRET probes (200 nM) in PBS buffer (pH 7.0) for 1.5 h. The resulting cell suspension (n 50,000) was directly analyzed by FC as described in Materials and Methods.(A and B) Histograms showing cell-count frequency vs. FRET intensity for each probe sequence
