ImmunoChemistry Technologies Annexin V-FITC Apoptosis Assay Kit

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).

Figure 1. Jurkat cells, grown in suspension, were incubated with 1 µM staurosporine for 3 hours at 37°C to induce apoptosis, and then labeled with SR-LEHD-FMK (Cat. 960/961) for 60 minutes at 37°C. Slides were prepared and imaged using a fluorescence microscope with a broad band pass filter. On slide B, cells appear very bright red, indicating a high level of active caspase-9 in these apoptotic cells. Non-induced cells did not fluoresce (slide A). Data courtesy of Dr. Brian W. Lee, ICT.

Figure 2. Jurkat cells were exposed to two experimental conditions (A and B). Each condition was treated with either DMSO (negative) or staurosporine (apoptotic), then labeled with SR-LEHD-FMK (Cat. 960/961). Samples were read in a fluorescence plate reader (550 nm excitation and 590 nm emission using a 570 nm cut-off filter). Staurosporine induced caspase-9 activity 3.3X in both conditions: Condition A (11.0 to 36.5) and Condition B (12.7 to 41.8). Data courtesy of Mrs. Tracy Murphy, ICT 8Y18.

Figure 1. Jurkat cells were untreated (A.), or were exposed to staurosporine to induce apoptosis and increase serine protease activity (B.). During the final hour of treatment, samples were stained with FAM-Leu-CMK (Cat. 949/950) for 1 hour at 37°C, washed, stained with PI for 15 minutes, and then analyzed using a flow cytometer. Staurosporine increased median fluorescence intensity for both FAM-Leu-CMK (BL1-H, x-axis) and PI (YL1-H, y-axis). Data courtesy of Dr. K. Strandberg (ICT 231:80-81).

Figure 1. Jurkat cells were treated with staurosporine for 1, 2, 3, and 4 hours to induce apoptosis and increase serine protease activity (green), or were untreated (gray). Samples were stained with FAM-Phe-CMK (Kit 945/946) for 1 hour at 37°C, washed, and then analyzed using a flow cytometer. The amount of serine protease activity detected positively correlated to the duration of the exposure period. Data courtesy of Dr. Kristi Strandberg (ICT 231:75-79).

Figure 2. Jurkat cells were exposed to staurosporine to induce apoptosis and increase serine protease activity (upper), or left untreated (lower), then stained with FAM-Phe-CMK (Cat. 945/946), 660-VAD-FMK (Cat. 9120), and Hoechst 33342. Imaged using EGFP (Ex 470/30, Em 530/50), Cy5 (Ex 620/60, Em 700/75), and DAPI (Ex 375/28, Em 460/50) LED filter cubes at 20X. Staurosporine increased the intracellular levels of both serine proteases and caspases. Data courtesy of Dr. K. Strandberg (ICT 231:73).

Figure 1. Jurkat cells were treated with DMSO (negative control) or 1 µM staurosporine for 2 hours to induce apoptosis. Cells were then stained with JC-1 dye. Normal healthy cells (two cells, upper and lower left) concentrate JC-1 in mitochondria and fluoresce bright orange. Apoptotic cells (three cells, right), with mitochondria of various stages of permeability, exhibit a reduced orange fluorescence and increased green fluorescence, as JC-1 disperses through the cells. (Dr. Brian Lee, ICT).

Figure 2. Jurkat and HL-60 cells were exposed to DMSO (negative control) (dark orange) or 50 μM CCCP depolarizing agent (light orange) and then incubated with JC-1 for 20 minutes at 37°C, and washed. Aliquots were analyzed in triplicate in a fluorescence plate reader set at 488 nm excitation and 590 nm emission filter settings. Healthy cells exhibited a high level of orange fluorescence; the CCCP-depolarized cells had reduced orange fluorescence as the dye dispersed. (Ms. Tracy Hanson, ICT)
