Coming soon: Far-Red FLICA Caspase-1 Detection Probe

ICT is pleased to announce the upcoming release of a far-red fluorescence-emitting inhibitor probe for the in vitro detection of activated caspase-1 (ICE) enzyme.

FLICA™ 660 Caspase-1 Detection Reagent, 660-YVAD-FMK, allows for the rapid and reliable detection of caspase-1 in whole, living cells. Perform multiplexing studies with blue-, green-, or orange-labeled biomarkers via flow cytometry and fluorescence microscopy. The far-red 660-YVAD-FMK fluorescent reagent joins its green fluorescent analog for active caspase-1 detection, FLICA FAM-YVAD-FMK, in the ICT FLICA range of fluorescent probe assay kits.

Caspase-1 (ICE)

• Originally identified as Interleukin -1β Converting Enzyme or ICE
• Cleaves IL-1 beta and IL-18 into active forms
• Creation of the inflammasome during host responses to pathogens leads to the activation of caspase-1
• Active caspase-1 plays an antimicrobial role during infection, leading to pyroptosis
• Inflammation-related disease models have illustrated a role for caspase-1 in asthma, rheumatoid arthritis, multiple sclerosis and other disorders

FAM-FLICA™ Caspase-1 Assay

This in vitro assay employs a fluorescent green inhibitor probe to detect active caspase-1 enzymes in living cells or tissue samples. FAM FLICA Caspase-1 Assay Kit, available in Trial (25 tests) and Regular Size (100 tests)
View assay details and data:


• Direct, fast labeling of active caspase-1
• Flexible analysis with standard fluorescence detection methods
• Green fluorescence allows for multiplexing with blue, orange, and red fluorescent dyes
