Figure 1. Jurkat cells were treated with staurosporine (Positive, Induced, right histogram). Negative control cells were spiked with a DMSO vehicle control (Negative, Non-induced, left histogram). Cells were stained with SR-VAD-OPH for 1 hour, washed twice, and read on a flow cytometer. Only 8.0% of control cells displayed caspase activity, whereas staurosporine induced caspase activity in 90.3% of the experimental cells. This is a ratio of 11:1. Data courtesy of Ms. Tracy Hanson, ICT 092713.

Figure 2. Jurkat cells were treated with staurosporine to induce apoptosis, then labeled with SR-VAD-OPH for 60 minutes. Cells were washed twice and wet-mount slides were prepared. A grey DIC image (left) was taken, and red fluorescence (right) was detected using a band pass filter (excitation at 565 nm, emission at 590-600 nm). SR-VAD-OPH reveals complete caspase activation in the form of red fluorescence in all cells. Data courtesy of Ms. Tracy Hanson, ICT (ICT111809; SR_OPH_111_17_18).

Figure 1. Jurkat cells were treated with staurosporine to induce apoptosis, and then labeled with FAM-DEVD-OPH (Cat. 6356). Wet-mount slides were prepared and green fluorescence (right) was detected using a band pass filter (excitation at 488 nm, emission at 520 nm). FAM-DEVD-OPH reveals complete caspase-3/7 activation in the form of green fluorescence in all cells. The corresponding DIC image is shown (left).

Figure 1. Jurkat cells were treated with DMSO (left) or staurosporine (right), labeled with FAM-VAD-OPH II, washed, and stained with PI. Four cell populations are seen: unstained live cells do not fluoresce (lower left); early apoptotic cells fluoresce green with FAM- VAD-OPH II (lower right); late apoptotic cells (upper right) fluoresce green (active caspases) and red (permeabilized cell membrane); and necrotic cells fluoresce red (upper left).

Figure 1. Jurkat cells were treated with staurosporine to induce apoptosis, then stained with FAM- VAD-OPH I (Cat. 6354) or FAM-VAD-FMK FLICA® (Cat. 92), washed and then read on a flow cytometer. Results with the OPH inhibitor (grey solid) are consistent with those achieved using the FMK inhibitor (green outline). FAM-VAD-OPH inhibitors mirror FAM-VAD-FMK analogs for apoptosis detection, and they may be less toxic and more stable. Data courtesy of Dr. M. Olin, University of Minnesota (ICT-202).

Figure 2. THP-1 cells were treated with PMA (5 ng/mL) followed by LPS (100 ng/mL for 1 hour, lower row of images), or were untreated (upper row of images), and were then immediately stained with 660-YVAD-FMK for 1 hour at 37°C (concurrent with treatment). Cells were then stained with Hoechst 33342 and imaged. Intracellular caspase-1 activity was detected using Cy5 (Ex 620/60, Em 700/75) and DAPI (Ex 375/28, Em 460/50) LED filter cubes at 20X.

Figure 1. Jurkat cells were stained with DAF-2DA dye (Kit 9155), washed, and then treated with DMSO control (left histogram) or 1 mM DEA NONOate, a nitric oxide donor (middle histogram). Cells were read on the FL1 channel of a flow cytometer. The median fluorescence intensity (MFI) of DEA NONOate treated cells was 3.5-fold higher than for the control cells. Data also overlaid in a single plot (right, black: Negative; right, red: Positive). Data courtesy of Dr. Kristi Strandberg, ICT, 227:76.

Figure 2. Jurkat suspension cells were stained with DAF-2DA dye, washed, and then treated with DMSO control (Panels A-C) or DEA NONOate (Panels D-F), a nitric oxide donor. Cells treated with DEA NONOate showed an increased level of green fluorescence relative to the untreated cells (Panels A v and D). Microscope images were obtained using a Nikon Eclipse 90i microscope with a Hamamatsu Flash 4.0 camera. Data courtesy of Dr. Kristi Strandberg (ICT 228:57-58).

Figure 1. Live cells with green fluorescence (right side of histogram) can be distinguished from dead cells (unstained, left side of histogram). Forward and side scatter graphs are also shown. Jurkat cells were stained with 1 µM Calcein AM and analyzed in a flow cytometer with a FL-1 99% attenuation filter. 93.0% of the live cells stained positive with Calcein AM (A, right), while 0.0% of ethanol-killed cells stained positive (B, right).

Figure 2. Using 7-AAD, live cells (unstained, left side of each histogram) can easily be distinguished from dead/membrane compromised cells exhibiting red fluorescence (right side of each histogram). Jurkat cells were stained with 7-AAD, and analyzed using a flow cytometer in FL-3. Only 4% of untreated cells (A) are dead compared with 97.6% of ethanol-treated cells (B).

Figure 1. Live cells exhibiting green fluorescence (right of histogram) are easily distinguished from dead cells (unstained, left of histogram). Jurkat cells were either mock-treated (A) or killed by exposure to 90% ethanol (B). Cells were stained with Calcein AM, then analyzed in a flow cytometer with a FL-1 99% attenuation filter. Most (93.0%) live cells stained positive with Calcein AM (A, right), while 0.0% of the dead cells stained positive (B, right). Data courtesy of Dr. K. Strandberg.

Figure 2. Mock-treated Jurkat suspension cells were stained with Calcein AM to detect live cells. The majority of the cells imaged were considered to be live and healthy. Panel A reveals green fluorescence-stained live cells. Panel B shows a corresponding differential interference contrast (DIC) image, which reveals cell morphology. Microscope images were obtained using a Nikon Eclipse 90i microscope with a Hamamatsu Flash 4.0 camera. Data courtesy of Dr. Kristi Strandberg (ICT 226:95).

Figure 1. FLICA® 660 was reconstituted in DMSO, diluted in diH2O, and analyzed on a Molecular Devices Gemini XPS 96-well fluorescence plate reader. The excitation spectrum (grey) was generated using an emission of 760 nm. The emission spectrum (red) was generated using an excitation of 600 nm.

Figure 2. Jurkat cells were treated with a negative control (left) or staurosporine, an apoptosis inducing agent (right), then stained with 660-VAD-FMK (Cat. 9120) for 1 hour. Cells were washed twice and read on an Accuri C6 flow cytometer. Treatment with the negative control induced caspase activity in only 8.2% of cells (left), whereas treatment with staurosporine induced caspase activity in 96.5% of cells (right). This is a ratio of 12:1. Data courtesy of Mrs. Tracy Murphy, ICT, 213:48.

Figure 1. Jurkat cells were exposed to DMSO as the negative control (dark orange bars) or 50 µM CCCP depolarizing agent (light orange bars) and then incubated with TMRE or TMRM. Aliquots (100 µL) were analyzed in triplicate in a black 96-well plate using a fluorescence plate reader (550 nm excitation and 580 nm emission using a 570 nm cut-off filter). Healthy control cells had a high level of orange fluorescence compared to the CCCP-treated cells. (Ms. Tracy Hanson, ICT).

Figure 2. Jurkat cells were treated with DMSO (control) (A) or staurosporine (B), and then dually stained with TMRM and the green FLICA® poly caspase probe FAM-VAD-FMK (Cat. 92) and analyzed by flow cytometer. In the staurosporine-treated cells (B), there is loss of orange fluorescence (FL-2) and a concurrent increase in cell-bound green fluorescence (FL-1) due to caspase activation. Treatment with staurosporine induced apoptosis in about 90% of cells (Ms. Tracy Hanson, ICT).
