• Apr 26, 2017 · cal microscopy and flow cytometry studies were employed to examine the involvement of these processes in the uptake of F-Ab40 by neuronal cells. Localization of a significantly large portion of F-Ab40 in the cytoplasm of PC12 cells and RPH neurons, distinctly separate from the acidic cell organelles labeled by lysotracker, is indicative of non-endocytotic uptake.
  • washed with PBS, flooded with fresh medium containing 100nM LysoTracker Red DND-99 (Invitrogen, USA) and incubated for 1hr in the dark at 37°C. Thereafter, the cells were inspected for Lysotracker accumulation by confocal microscopy (Leica TCS SP5) and flow cytometry (BD FACS Calibur). γH2AX immunostaining for DNA damage
  • The integrity of the lysosomal membranes was assessed using lysotracker (Molecular Probes) staining or acridine orange (AO) relocation test, as established previously. 15 In brief, after different treatments, cells were collected, stained with lysotracker (75 nM for 25 minutes at 37°C), and analyzed using flow cytometry (BD Biosciences), and ...
  • Powerful Flow Cytometry With 12 detection channels and up to four excitation lasers, the FlowSight can measure up to 10 fluorescent probes simultaneously with unrivalled sensitivity. Numerous thoughtful design details like a dedicated side scatter laser, adjustable laser intensities, and brightfield imagery for the direct measurement of cell size
  • Description. LysoTracker® Red DND-99 is a red-fluorescent dye for labeling and tracking acidic organelles in live cells. The LysoTracker® probes consist of a fluorophore linked to a weak base that is only partially protonated at neutral pH. This allows LysoTracker® probes to freely permeate cell membranes enabling them to label live cells.
  • Jan 23, 2019 · c Mean fluorescence intensities (MFI) of LysoTracker in HUVEC without treatment (vehicle) and treated with MPs and MPs-ICs for 24 h and acquired by flow cytometry. Wilcoxon test, * p ≤ 0.05, n = 4.
In contrast,flow cytometry reveals significant fluorescence for peptide 2 in M21 cells but not for av deficient M21L cells (Figure 2A). Contrary to peptide 1,the negative control (no peptide) largely overlaps with the 0min samples. Fluorescence imaging confirmed the presence of peptideinside the cells by z-stacking(Figure S2).
LysoTracker Green staining combined with flow cytometry was recently proposed for the enumeration of aquatic HNFs. Here we show that LysoTracker Green not only allows the enumeration of HNFs in estuarine samples with a wide range of HNF abundances, but also allows the discrimination of distinct HNF populations in mixed assemblages.
Next, the cellular ROS level was measured by flow cytometry as described previously . As shown in Figure 1(c) , the populations in higher fluorescence intensities significantly increased by ~10% after the exposure of DpdtpA to the cells for 24 h, but the addition of NAC, a ROS scavenger, significantly decreased ROS production (~23%), hinting ... Jul 27, 2012 · A reduction in the interaction of the two clones with the macrophages was detected by flow cytometry. Monoclonal antibodies were produced and used to demonstrate the presence of these proteins on the bacterial surface of the corresponding clone, and on the H. parasuis phagocytosis-resistant strain PC4-6P.
As in LysoTracker? dye–stained cells, the lyso? dye–stained cells may constitute only a small portion of total cellular fluo? res? cence, making it difficult to quantitate the number of lyso? somes or their pH by flow cytometry or fluorometry. LysoTracker? and LysoSensor? Probes? |? 2 Figure 1 The pH-dependent spectral response of LysoSensor?
My knowledge on flow cytometry is limited. So that it would be great if you are able to recommend some paper or protocols to follow especially these kind of living staining. Thanks in advance. The fluorescence of LysoTracker reflects the amount of lysosomes. Flow cytometry plots with median fluorescence and diagrams with fluorescence intensity related to DMSO-treated cells (0 µM Ecdy) are depicted. Results are calculated as the mean ± SEM of three experiments. *p < 0.05; **p < 0.01.
Dilute the marker (e.g., Lysotracker, mitotracker, or Golgi marker) in serum-free HEPES-MEM in a tube and mix it well. (1-2 uM final concentration; 1.5 - 2 ml per 35 mm dish) Gently rinse the cells after transfection with serum-free HEPES-MEM and add the medium with the markers into the plate carefully. Incubate the culture for 20-25 minutes at room temperature. Jul 28, 2017 · (A and B) Uptake of 50 nM Alexa 488–coupled hY4 fragment (hY4 31 nt) was analyzed by flow cytometry (A) and confocal microscopy (B) (representative of three independent experiments each). Blue, nuclear staining with Hoechst 33342; red, staining of acidified endosomes and lysosomes with LysoTracker DND-99; green, Alexa 488–coupled hY4 fragment.
