FAM-FMK

 

Carboxyfluorescein Caspase Detection Kits™: 

Apoptosis detection and in situ labeling of active caspase in live cells. 

 

  

1.  Key Benefits

 

•  Non-cytotoxic assay arrests further apoptotic activity via caspase inhibition 

•  Cell permeablity permits direct visualization of cytosolic apoptotic events 

•  Apoptotic cell population does not diminish over time 

•  Add reagent directly to cells. No special buffer or media needed. No preparation of cell lysates required. Simple wash procedure 

•  Works in diverse cell lines: human, rodent, Drosophila 

•  Can be performed in conjunction with Annexin staining, TUNEL, antibody staining, or with other APO LOGIX reagents on the same 

   population of cells 

•  Permits high through-put screening. Protocol can be adapted for ex vivo as well as in situ experiments 

•  Yields both quantitative and qualitative results. Gives strong signal with little background noise 

•  Mark activity across the range of caspase proteins. Poly-caspase and caspase-specific assays to target caspases 1, 2, 3, 6, 8, 9, or 

   10 are available 

•  Applications – Flow Cytometry, Fluorescence Plate Reader, Fluorescent Microscopy

 

  

2.  Assay Principle 

 

APO LOGIX Carboxyfluoroscein Caspase Detection Kits label active caspases in living cells undergoing apoptosis. Cell Technology’s probes utilize carboxyfluorescein(FAM)-labeled peptide fluoromethyl ketone (FMK) caspase inhibitors (FAM-peptide-FMK). These FAM-peptide-FMK compounds are both cell permeable and non-cytotoxic during the course of the assay and thus allow the detection of active caspases in living cell systems.
