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 1. Monocytes can secrete active caspase-1, therefore cells were labeled with FAM-FLICA® Caspase-1 (WEHD) (cat. 9161/9162) prior to treatment. Cells were then treated with DMSO (control) or 10 µM nigericin (cat. 6698), stained with Hoechst 33342, fixed (cat. 636), and viewed using EGFP (Ex 470/30, Em 530/50) and DAPI (Ex 375/28, Em 460/50) LED filter cubes at 20X. Increased levels of FAM-FLICA® staining were seen in the nigericin-treated cells. Data courtesy of Dr. Kristi Strandberg, ICT (235:60).

Figure 1. The process of autophagy is an intracellular degradation process during which cytosolic organelles and materials are enclosed within an isolation membrane to form an autophagosome. The outer membrane of the autophagosome fuses with the lysosome. The sequestered material is subsequently degraded within the autolysosome.

Figure 2. Cells were either untreated (Black) or treated with 0.5 µM Rapamycin (Orange), 10 µM Chloroquine (Blue), or both 0.5 µM Rapamycin and 10 µM Chloroquine (Red) for 18 hours. After staining with Autophagy Probe - Red Fluorescent, cells were washed and analyzed by flow cytometry (561 nm excitation and a 610/20 emission filter). Treatment with rapamycin or chloroquine increased the fluorescence signal compared to the control. Data courtesy of Dr. Kristi Strandberg (ICT 228:37-40).

Figure 1. R110-(RR)2 was reconstituted in DMSO, diluted in an aqueous buffer, and then spiked with cathepsin B enzyme and incubated at 37°C for 1 hour. After incubation, fluorescence was analyzed on a Molecular Devices M5e plate reader. The excitation spectrum (black) was generated using an emission of 590 nm. The emission spectrum (green) was generated using an excitation of 460 nm.

Figure 2. Jurkat cells were treated with the cathepsin inhibitors CA-074 Me (blue) and E-64d (gray), or were untreated (green) and then stained with R110-(RR)2. Samples were then analyzed analyzed by flow cytometry (488 nm excitation and a 530/30 emission filter). Treatment with CA-074 Me or E-64d decreased the fluorescence signal detected compared to the untreated control, which displayed a baseline level of cathepsin activity.

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).
