Biotium offers a wide range of fluorescent probes for studying apoptotic cells:
The
NucView® Caspase-3 Substrate comes in 3 colors, and measures caspase activity in real time, in live cells.
MitoView™ 633 can measure the decrease in mitochondria membrane potential that occurs in early apoptosis.
CF® Dye Annexin V conjugates come in many color options, and label PS on the membranes of late apoptotic cells. We also offer kits containing combinations of these probes.
