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 (Cat. #1067-100, -400) and 2X Reaction Buffer (Cat. #1068-20, -80) for caspase assays are also available separately. MW: 727.7. Purity >9
