ICT’s caspase 6 FLICA™ kit measures active caspase 6
inside whole living cells. It is NOT an
ELISA and does NOT use antibodies.
What's
in the kit?
The kit contains: the caspase 6
FLICA™ probe (FAM-VEID-FMK); 10x apoptosis wash
buffer (which does not lyse the cells); Hoechst
stain (a blue DNA stain); propidium iodide (a red
live/dead stain); and a fixative (which is used
after labeling the cells).
How
does it work?
The FLICA™ reagent (Fluorescent Labeled Inhibitors of Caspases)
is comprised of 3 segments - it includes: a green
(FAM =carboxyfluorescein) fluorescent label; an amino acid peptide inhibitor sequence targeted by active
caspase 6 (VEID); and a fluoromethylketone group (FMK) which acts as a leaving group and forms a covalent bond with the active enzyme.
The caspase 6 FLICA™ reagent
is cell permeant, so you don’t have to lyse or permeabilize the membrane to get it into the cell. Just culture your cells, add the FLICA™ probe to the media, incubate, and wash the cells. If there are active
caspase 6 enzymes, they will bind to FLICA™ and retain it within the cell, thereby capturing the fluorescent signal.
The FLICA™ probe constantly
fluoresces, therefore any unbound reagent must be washed back out of the cell to remove any background noise. This is done by several quick rinse and spin steps, or further incubation with the wash buffer or
cell culture media. Click here to read our

How
do I read my cells?
The resulting positive fluorescent signal can be
detected with a fluorescence |

microscope
(see newsletter
Figures 2, 3, 5a, 9), a fluorescence plate reader (Figure
10), or a flow cytometer
(Figure 7). The green FLICA™ probe, FAM, excites at 490nm and emits at 520nm.
How
many cells do I need?
You can detect caspase 6 activity in individual cells (Figures 1, 2, & 6) or culture them up to
1x106 cells/mL and read them using a fluorescence plate reader or flow cytometer (Figures 3 & 5). They also work with adherent cells (Figure 6).
What
kind of cells can I use?
FLICA™ kits have been used successfully with
many types of cancer cells; glial cells, neurons,
primary cells, epithelial cells;
endothelial cells; macrophages; and other types of
human, mouse, rat tissues, and many other species.
It will not work in previously fixed
cells or paraffin cells, as that treatment
inactivates the caspase 6 enzyme. See our accessories
page for a caspase 6 antibody and other reagents.
What
other kits do you have?
To detect apoptosis in general, use the green or red poly
caspases kits. These kits use a general peptide sequence
(VAD) which reacts with all active caspases. To target
other specific caspase, ICT offers
several green FAM-FLICA™ kits which react with different caspases (caspase
1,
2,
3&7,
8,
9,
10, or
13) and red SR-FLICA™ kits which react with all caspases, 3&7, and
caspase 9. Use the red and green kits together and with our serine protease and cholinesterase kits for dual-labeling studies (Figures
5, 7, & 9). |
