Comment |
Ready-to-use fluorometric substrate for caspase-6 and related caspases that recognize the amino acid sequence VEID. Caspase-6 and related caspase activity can be quantified by fluorescent detection of free AFC after cleavage from the peptide substrate VEID-AFC at Ex/Em = 400/505, using a fluorometer or multi-well fluorescence plate reader. Alternatively, a shift in fluorescence from blue to green upon cleavage can be visualized, using a hand-held long-UV lamp. The ready-to-use caspase substrate provides an economic alternative for researchers who perform large amount of caspase-6 assays. Cell Lysis Buffer for caspase assays are also available separately. |
Protocol |
1. Induce apoptosis in cells by desired method. Concurrently incubate a control culture without induction. 2. Count cells and pellet 1-5 x 10^6 cells or use 50-200 μg cell lysates if protein concentration has been measured. 3. Resuspend cells in 50 μL of chilled Cell Lysis Buffer containing 10 mM DTT to each sample. 6. Add 5 μL of the 1 mM VEID-AFC (50 μ M final conc.) into each tube individually and incubate at 37 °C for 1-2 hour. 7. Read samples in a fluorometer equipped with a 400-nm excitation filter and 505-nm emission filter. For a plate-reading set-up, transfer the samples to a 96-well plate. You may perform the entire assay directly in a 96-well plate. Fold-increase in caspase activity can be determined by comparing these results with the level of the uninduced control. |
